As a Canadian engineer and general contractor. I could have told you this guy is not in the construction field . he knows absolutely nothing about construction and is not someone you should take advice from. The new white blocks he showed, is called AAC blocks. It is much lighter than the cement black and absorb much less water than the cement blocks. That does not make it better, or more structural, it is just easier to work with. Faster to produce and very expensive. The strength of a building structure does not depends on it's wall enclosures, it is the design and building of the Footing, foundation walls and all RCC system that determines the strength. I won't be surprised if the intention of the video is for Nigerians to buy blocks from a new company he is a part of.
You said it all he knows nothing about building only just talking in the of i too know
But do you refute the facts he said about the cement bricks?...
Such a profound detail.
A bunch of Thanks man
i don't think he is promoting a product, just ignorance... he is not knowledgeable on buildings... but his intention is genuine...
From the moment I saw him I knew he isn't an engineer.
The house that fell has bad foundation with managed materials. It's a bungalow converted to a storey building.
In the United States you have to fill those holes with rebar and cement, which makes a building strong enough to survive tornadoes and hurricanes. I was born and raised in Los Angeles and I'm interested in making my own cement brick manufacturing because it's so profitable and very practical
You sound like a Business Man. Somebody with a sound KNOWLEDGE of Engineering and Engineering Materials will tell you that GOOD Concrete ( Concrete made of 50% or more Cement, 40% or less Sand ) is as STRONG as Diamond. These are used to make Roads in USA. USA has the BEST Roads, Sir. Nigerian Roads made with Asphalt, Coal Tar ,Gravel and Binders are no where near US Roads in terms of Strength and Resistance to " WEAR" ( eroding away from the sides and development of "pot holes" in the middle of the Roads ).
Sir, it looks like you saw the EFFECT of "POOR QUALTY" Blocks. Blocks that DO NOT have the RIGHT amount of Cement. ( Probably 20% Cement ). Quick test of a GOOD Block is: Can it crack a Palm Kernel Nut? If it cracks a Palm Kernel Nut without ( the Block ) breaking, then it is a GOOD Block.
Consult Material Science Engineers or Mechanical Engineers on this issue. I live in California, USA ( Studying Engineering NOW).
But USA don't build their house with cement or blocks
@@Richtobi says who?
@@Richtobi Here in Florida certain parts build with concrete due to hurricanes and tornadoes.
Did the Dr. talk about the strength of the bricks? If you can't talk about moisture absorption then there's nothing to refute...
Diamond lmao okay, US doesn't have the best roads, they are just really good at maintaining what they have (maintenance is key). Nigeria should build houses with bricks, wood, or steel while having a good architectural layout to avoid building terrible houses.
I actually thought you were going to recommend a better alternative.
Nothing to learn from this video.
Same thing i thought till i gave Up. So Long Outlining a Problem without possible Solutions and Alternatives. Was a Waste Of Data.
Actually in new York City. They use cement block. But this blocks are very strong... Like it can drop from 20ft and still not break. He didn't speak from an Engineering view. ... I'll say we in Nigeria need to apply ASTM AND ICC code and requirements.
@Anthony Famobiwo; Problem is you were not paying attention or wasn't patient enough to watch till after 8:05 min. He said "we need blocks that are waterproof and blocks that don't collect fungi". He also gave examples of blocks that are used in Israel and Brazil. In simple terms, his alternatives are waterproof blocks and blocks that does not permit growth of fungi. The interesting aspect is that a waterproof block will not support growth/spread of fungi since fungi need moisture to grow. These are non-complex options. Simple painting of walls with water-proofing paints or sealers is enough. Nigeria is a country where people just stay static, no improvement or efforts to improve and make things better. You heard what he said, that he is not even an engineer but he knows what the solutions are. For example, am a scientist but have to come with a technology that solve major land/property problems in Nigeria. Often I asked myself, what are the stakeholders in these different industries doing. Everyone is blindly running after money which eventually bring unlucky victims and even them back to square one. Nigeria "tire me o".
Same here!
@@ADE-of-LAGOS Trust me when I say to you that lots of stalkholders in the industry ain’t running blind in any form or shape, even though a lot might think so. Nigeria is unfortunately a country without good leadership and government.
Is easy to have an idea of how things can be done better but when it gets to the point of implementation, it’s a different ball game. Loads of this other better alternatives to building houses in Nigeria ain’t easily accessed in terms of raw materials which in turn makes it far more expensive to procure. In a situation where private citizens are trying their best to provide low cost housing scheme, how do they provide such solution at a higher cost?
If only our government have some things in place like the countries mentioned then, we could have some of these conversations but for now we can only deal with what we have. Because it’s just what it is.
My 2cent.

This is a typical display of ignorance. Materials usable in tropical environment may not suit temperate region. Nature determines what human in their knowledge and instinct uses for shelter. The collapsed building shown was built by quack, unsupervised and may be for a stingy client. Failed structural elements caused the collapse and not the blocks. Kindly do your findings before you talk about issues you know nothing about.
he mentioned waterproof blocks and he said the engineers should look into this matter
Your reply is also misleading. Walls are part of the load bearing aspects. Why do Nigerians blindly refuse criticism? He is right about Cement blocks not being sustainable choice of building material
Dudes lost
@@emipodro9685 Boss, there's nothing like waterproof block... Don't repeat it again. Cement even needs water to harden.
@@webcityztv Blocks are not meant to support slabs. That would be a bad construction. Columns are meant to support and not blocks
As a Structural Engineer, hollow blocks have nothing to do with building integrity and stability, especially when your building is framed (columns, beams and slab). The blocks are non-load bearing walls and they are only used for partitioning. In a case when your building is not framed (quite rare), then your blocks are designed to be load bearing. We should stop mis-informing the public and allow professionals to discuss sensitive issues like this. The collapsed building shown in the video was as a result of foundation failure through intense water ingress as a result of the flooding and has nothing to do with the cement blocks Finally, cement blocks do not support any structural load in a framed building. Don't get it twisted.
Please, tell him again o!!!... maybe, just maybe it will sink...
Really? but in many cases block are used to carry loads, because some of these frame materials and sizes are reduced to save money, so these are facts and not mis-informing. We need to improve on the ways we are doing things in Nigeria, we have no standardized way of doing things. Every engineer, contractors or builders have their own standard. It's time we look for better alternatives and let stop this sentimental bias and em braise new developments
@@lanrusel07 Blocks are NEVER used to carry loads in a building except the building is designed with the concept of load bearing walls which is rare in Nigeria. Blockwalls are primarily used for partitioning, fill-ins at the Iintel areas. That is why during renovation, blockwall partition can easily be knocked off while the building frame is still in place.
@@adedejidisu5471 Thanks for contributing your expertise.
I hope he gets to read this comment. He needs feedback
I’m really happy a lot of people in the comment section are well educated and not listening to this misinformation
I would advise you leave engineering topics alone because it's obvious you don't know what you are saying.
Here in USA and some country i've visited in South America they're still using cement blocks too for building, but the difference is that the blocks they using is 4inches and solid with strong pillars in the building. Why in Nigeria they used 9inches and 6inches cement blocks with low material for building.
This guy doesn’t make sense, his examples are all contradicting.
I am surprised you didn't mention one method that could be a solution.
at least he gives you an idea, if you never considered this problem
@@emipodro9685 Collapse is not due to cement block.
@@emipodro9685 Since he said it's outdated... He could have told us the one that is in Vogue. Does he want all building to be concrete
Another building collapsed in Lagos killing 2; be fighting Adelaja , or are you waiting for the oyinbo people to tell you, why do we have to get every innovation from others
so what do you think the problem is and why are we still having the same problem and nothing is been done to stop it. all he wants is innovation that how we will develop
Your findings are on Buildings produced by quacks. As a licensed Builder (specialist in Building production), I have executed safe buildings. All these buildings in the UK are made to last because of technology and Professionals. What Nigeria needs is the right law that should regulate all activities related to Building production.
I am glad you Wade into this topic even as a layman.
You cannot mortgage the life of your loved ones to quack doctors,same should apply to Building production.
With due respect to all other 6 professionals in the building industry,the Builder is not given the right place of priority in the building industry. This is the main Crux of the matter.
it about time we moved away from old fashioned blocks the world is moving fast, look at what other countries are doing
We have the law but no enforcement. The building control officers are only interested in money. No one cares about what is going on during manufacturing of cement blocks as well as during construction. You can get approval for anything as long as you have the cash.
@@emipodro9685 👍🏿
thank for informaing this man pleases the building construction is not properly regulated by the building authorities in what way should a qackes be allowed to take a construction project and the 6 proffectionals are only persons that are worthy to take and sign up a conttacts is not what is causing the building collapse bad regulations and management Nigeria as a whole
I can't believe I just wasted 10 minutes of my time
Same I can't just understand all what he is trying to say.
🤣🤣🤣🤣🤣
I wish I can click 👍🏾 50 times over for this message from DSA. So necessary. I have told colleagues, friends and people I know that blocks are not needed anymore. Especially for residential buildings.
Thank you DSA for this.
If blocks are not needed anymore, then what are actually needed!?
Blocks aren't bad,there is a minimum strength requirement for blocks but here in Nigeria ,there is no regulatory actions to control who should be in the business of producing blocks. When you don't have the right law and it's enforcement everything goes wrong. Talking from a peodesional's view
What of cement for pillars or flooring.???
This man has no common sense at all ooo, talk about cements mixing ratio and shut up.
We where waiting for you to suggest a better alternative and you only lamented like a little girl.
If houses are built like bridges then houses will never collapse.
Third mainland bridge is strong and will last because of proper cement mixing ratio and the foundation laid down.
Mr Businessman do your research well before coming out next time.
And for your information I will neither like nor share this garbage.!!!
@@AbiodunOOJO when you use the Autodesk Revit software to design you will realise that block is not even considered for either internal or external walls. It will give you the different materials and components used for walls in buildings today.
🙏 did you know that Water actually makes cement harder but the method you use and the type of cement and the type of sand cement has to be perfectly dried and then it will stay hard as rock . ❤️💛💚🇯🇲🔥
I'm not sure if its the same technique we use tho
Blocks don’t hold buildings, the pillars does. Please research more
Where can the Nigerian masses get those blocks?
I couldn't agree more with you Henry. The Chinese he mentioned, what do they do? They slap a giant steel into the ground to form a bunch of pillars then the wrap it up with glass. Guess what? Your building is ready 😂. So you're right about pillars beithe main thing, not really blocks
The man was talking about issues he knew nothing about. Shameful
And the Pillars are made up of what?? LOL
JEREMIAH DUROTOLA concrete
It is good when people stay in their lane Pastor. Better to research things before talking on the topic.
Lol
Describing the problem is 1/2 of the solution, a good follow up video would be a video presenting alternative solutions to problem and then we can start sharing that video
while, I appreciate what you pointed out concerning the hollow blocks adding unnecessary pressure on the foundation. Yes the man is not an Engr. by profession, but that doesn't mean that the did not make any point. it is true that there are other block that are lightweight and stronger than our hollow blocks.
This is not correct. Concrete is the most widely used building material throughout the world. The problem in Nigeria is that the right mixture of concrete is not used and the result of this is substandard blocks that makes building to collapse easily
What do you want us to build with
The right word is building frame. The frames are the beams, columns and roof structure. These can be steel, concrete, timber or any other type. The block wall is just the cladding. If a building collapse, we will look at the frame and type of foundation. The reinforcement bars will be questioned. Concrete blocks are also used in the western world. Thank you.
Wall is not cladding oh! Cladding is like decoration on wall. However, I agree with you that there are various elements of the building that provide structural strength
Jamaica houses are made of cement blocks we don't have houses collapsing. We have strong houses. Those houses are not properly constructed use of inferior blocks
Thank you. Many of my grand parents have inherited homes that date 5 generations back. No issues. Hurricane season come and go.
I now live in the US and the home I have have many issues, it’s a constant work. I would rather cement and block, but I understand that cement and block may not work in every areas of the world due to different climate.
Seen a lot of fault in construction during building collapse. From all indication the building lack proper structural reinforcement and in addition the speaker man shows his ignorance's .
even in nigeria you dont see housing collapsing like this frequently, like you have mentioned they use inferior materials that is why
@@auroraautumn8764 Agree, something else is wrong.
Im from Zimbabwe and for generations we pass down brick houses. Nigerian engineers need to look at their designs.
What's the best option available and easily affordable for Nigerian community
Discuss
You may have a point there but people only Built houses with what they have access to. For example a sheet of plywood make cost $25 in States to be shipped to Africa it will cost 400 to $500 perf sheet when adjusted 2 foreign exchange rates
Chinese are building in 5 days, but those buildings reportedly have had many issues. The famous hospital builds during COVID is falling apart.
I’ve seen homes built in the Caribbean with cement and block. These homes have outlived over 4 generations. No rain, sun, storm, hurricane have lived them. Hence, the problem can’t just be cement and block.
also in Nigeria that he's criticizing
But as a Nigerian living in the north east of the nation.
How will one get those waterproof block at cheaper price.
Am well impress with your explanation and insight.
MR MAN, SAY WHAT YOU KNOW. STOP HANDLING TOPICS YOU KNOW NOTHING ABOUT.
Una go get sense
Is his usual way
I felt ashamed for him. He lost tracks
I'm not an expert in building but I do sometimes question the advantage of using hollow cement blocks for building in Nigeria. In developed countries, red bricks are used. They are cheaper. Like the pastor is suggesting, we need rethink building materials to maximise funds.
Not the blocks we used them in Jamaica and we never have building s falling down.The foundation has to be deep and strong.
New technology must be taken in account, but building with older method should no be neglected 🇹🇿
Buildings collapse because they are not well built, as simple as that. This guy has no idea what he's talking about
Honestly, this guy should stick to bible preaching. And as to why buildings collapse in Nigeria, a session with a qualified structural engineer will open up his mind.
This is 12 minutes of my life that I can't get back!!!
🤣🤣🤣🤣🤣
Luckily I only made four minutes.
😂
Dr. Sunday please keep to your lane, Western world still build with blocks, bricks, concrete walls etc, what matters is the consistency/ratio, weather considerations etc
Assuming the collapse video is not screenplay, the building collapse shown cannot be due to concrete block soaking up water. In fact concrete should get stronger with water. The reason for the collapse is most likely due to poor foundation design or choice without giving adequate consideration to soil conditions. If the foundation was designed properly the building will not collapse in flood. However, I agree that architects should start looking at using other materials for facade instead of block work.
Are we permitted to see on your House and see what u have used in its construction?
he does not live in Nigeria, & it is just his opinion
Lol. Lol boss you done kill am
Dot mind him
Some haw he manages to fool a lot people
@@emipodro9685 No wonder. He was speaking on issues he clearly didn't research well into. Nature determines what human uses for shelter.
This loud mouth clown doesn't own a house. He's a renter.
So I read comments and thought it can't be that bad right.. But I watched few minutes into it and realised.. Yeah, it is as bad.. Don't bother.
I don't agree with this school of thought. I live in London which is part of Europe. There are very mouldy houses in London. There are rats and cockroaches also. The only thing is they maintain, they pull down their old buildings and rebuild. Thank you.
To collaborate you, the partitioning in UK are also light and you can hear sounds and movement from your neighbour's flat. There are also issues of moulds everywhere in UK apartment.
how old are these houses you are talking about? some of them are hundreds of years old
Hi Emi Pedro,
Not all the houses are 100 years old. Gone are the days they wait for 100 years before they pull a property down. Not nowadays that UK is filled up to the brim with people especially London. For example, when the white are taking you round their building, they will tell you a property was built in 1800 0r 1900, however, you will realise that they have not left the building for 100 years running, without maintaining or modernising it. For example, the House of Parliament, did you know how many times they have carried out a major work on it? Yet, they will still tell you that it was built in 1700. Please kindly Google their major buildings and confirm what I am saying. I am talking of the UK especially, England. Thank you.
What is this man even talking about? Cement is the best performing material in water and it actually strengthens over time.
What he needs to be talking about is to make sure that contractors don't try to cut corners by mixing too much sand with the cement.
I am a civil engineer. I am not sure what he is.
Quality control and assurance 💯
when you need a professional advice on building ,you consult an expert in that line.
Do you have any issue on his points, let's know and stop talking in parables
Experts don't have monopoly of Knowledge. Experience and research matters alot.
I'm a Civil engineer and sir with all due respect, you know nothing about structures and how they behave. I wont start making rubbish of what you said but please do not pass wrong information just for the likes.
Thanks
He is clueless about civil engineering but talking about it. horrendous! Did not even say what people should use as an alternative. But this was just really really BAD!!!
If you are really a civil engineer then you would know that the industry continously evolves. This man has a point concerning the effect of concrete blocks and the effects of fungi which creates mold. This is also a problem with buildings in the 🇬🇧 UK
My father's house is over 50 years without cracks.
It's not everything critiise especially when you don't understand the logic behind a design or concept.
I understand. your position but your father's house doesn't represent what is happening today.
Guys,just move to europe or america...leave the outdated tech to us ...we love cement... it's more solid than the toy homes in the western world...
Not true. They have buildings of 100years and above in Europe. No collapse. Him however has no Engineering knowledge.
I'm ashamed of what you said. block is just to cover and divide or partitioning,
what carries a building is the pillar
you re also making a mistake by saying a pillar carries load in a building instead of saying a column. Pillars have no steel reinforcement whereas columns have.
He suggested an idea and people started insulting comments, I for one I like and appreciate your observations, It is over to our Civil Engineers and technicians together with designers to respond intelligently, this is a challenge to them to prove that they are qualified professionals.
All those bricks he's mentioning are made with cement....
He talks against cement and suggests same cement again and again😬
Pls Nigeria will not use wood to build with the insecurity problem facing her. Fungi happened also in Europe, I'm in America and I dont envy their wood houses at all just that the civilized world maintain theirs, pls this argument is baseless period.
You need to learn about the Jamaican construction method. We used concrete block and we never had a building collapse there, and there we have Earthquake there at times
I believe that the pastor is trying to inspire our thought process on ways forward but the presentation was a little general.
Actually, there are many material alternatives that are better than hollow blocks that have better heat transfer benefits looking at our environment .
Modern building no longer use blocks as load bearing to prevent building collapse rather reinforced structures supported with beams and columns from foundations . With light weight bricks or precast walls.
I believe building material alternatives and availability is a reflection of low level of industrialliazation of the country and looking at ease of building construction on most advanced nations it's a mix of diverse materials that comprises of wood, glass and concrete. and drywall those materials are mixed based on the application requirements. Either to withstand heat or cold temperatures with lagging material mix.
For Nigeria the use of block is ok but focus need to shift from using those blocks as load bearing rather as partition for internal separation between rooms and therefore focus on lighter blocks of 3-6inches to reduce building dead weight. Clay is another good material in a high temperate climate and needed to be encouraged.
Great levels of deforestation in Nigeria
Mumu man! I disagree with u mad man. Use wood and build make armed robber come burn ur house lol. Are u the one mixing or laying blocks? Hahahahaha! Jack of all trade master of non.

Good explanation but he just keep repeating himself
Concrete, if properly made can live indefinitely in water, for instance, the concrete wave breakers in the sea...
Unfortunately he didn't explain the solution, I waited till the end for solution. At last he disappointed me. I expected much more from him, a more vividly accessible demonstration.
Me too people like are fake pastors
Thank God I saw this before watching till the end. So he really spoke about the problem all through! He could have done better for sure.
He identified no compelling problem. Everything he mentioned can only exist when a structure isn't built properly.
Dr.Sunday Adelaja, I disagree with your point of view. I live in America and houses in America are built with woods all over. The woods get rotten, filled with roaches, insects, and yet, Americans keep building houses with wood. Sir, Brick and blockhouses are the best. I think what you are misunderstanding is the type of cement used. There are houses in Nigeria that are more than 100 years old built with blocks. Check your facts again. Wooden houses in America fall apart when it floods heavily and when foundation cracks. So, your facts are not accurate. Nigeria Block and bricks pattern of building houses is the best, better than American wooden houses. I live in America and I will tell you all day.
Do you know how long the Chinese take to prepare the glued material inorder to build in five days?
It's amazing that we are on TH-cam criticizing someone pointing out the primitive technology we still employ to build houses in the 21st century, yes, it's way too outdated. All we need to do is do a little search on the same TH-cam and we will find out for ourselves that, our methods are not only outdated but too expensive. Doesn't it ring a bell in our heads that foundations which are supposed to be the strongest part of any building are cement mixed with concrete? That's pretty much where the use of cement should end, except in rare cases....but in naija even our decking for a building with just one structure on top, we use cement and concrete for the decking, what a waste of time, money and efforts, wood, steel and other less expensive and more breathable materials is all we need.. We all know that those cement blocks buildings can't breathe so they are hot as hell, and most of African sit under the sun, so the heat is unbearable. If we had constant supply of electricity all our money would be going to paying electric bills to keep those cement blocks buildings cold. The other part is when you used cement blocks it's almost too heard to change your structures partitioning, but if other materials like wood and drywall are used you can easily navigate through that process. Anyway, I would like to see our engineers become more innovative and stop being afraid to try something new. Be an engineer, think like an engineer or scientist that you are and stop behaving like robots.
Using of blocks is not the problem here oga. The problem we’re facing is people trying to manage materials for construction. When you don’t have a solid foundation, and when your building materials are not properly used then you will have problems. My father’s house was built to lintel level before I was born, we have completed the building and are living in it till now it’s still as solid as if it was just built!
YOU'RE WRONG THE PROBLEM IS THE CHEAPNESS OF NIGERIANS TO BUILD HOUSES AT ALL COST INSTEAD OF QUALITY BUILDING THEY USED 1 BAG OF CEMENT FOR 100 BLOCKS .
TELL ME WHY BUILDING WILL NOT FALL? IF YOU WANNA HAVE A STRONG BUILDING THEN 1 BAG OF CEMENT SHOULD ONLY MOULD 10 BLOCK SO THE BLOCKS WILL BE SOLID AND STRONG.
I actually understand the direction you are coming from. It’s good to have different and diverse techniques in architecture works in Nigeria mostly. Cement is for building houses and it must be a quality cement. Dangote cement is not good at all for building but Nigeria with its impunity has boosts it. Go to common Benin 🇧🇯 republic or Togo 🇹🇬 and see the differences in cement and building techniques, very simple and effective
Oga Ade. With these few points of yours, you have successfully confused us. 😅
Femi Fapohunda Hahahahahaha seams real confusion though.
🤣
He confused himself bro
No,I rather think he is confusing himself dis time
😂😂😂😂🤣🤣🤣🤣🤣.
buildings in Nigeria is looking old because they dont spent money to renovate the houses, everything thing need maintenance, putting food on the table is paramount to Nigerians than good looking painted houses... also very rare to find fungi in Nigerian houses except the exterior because is expose to rain... but the inside unless the house is leaking is dry because of the heat... fungus in houses is common in Europe because of winter and constant rain...
DSA I listened to you and agree with you that cement bricks are obsolete with many cons BC the building we started last year had setback BC it's raining and d bricks couldnt dry on time, some even got spoilt. Meanwhile, I did not hear you advice the exact technology you're talking about. All those buildings you mentioned & showed in Europe, what do they use to make d bricks? You should have researched and shared here. Thanks
They use wood. They have foundation of different forms. Depending on countries but like New Zealand they use Pile and strip foundation. Structure is modular or offsite construction.
I am not a civil/structural engineer but building with cement and block is stronger than building with wood or Sheetrock . In America and U.K , most residential buildings are created or made from Sheetrock (wood) . A house built with wood or Sheetrock cannot last 100 years. Using steel and other structural materials such as beams and very thick rods will help ensure a very solid and strong foundation . Using qualified structural engineer without cutting corners will reduce or eliminate building collapse in Nigeria . Let the engineers tell us the way forward . DSA did not tell us about the solutions to this problem . Thanks
I agree with you
I am a licensed Builder in Nigeria.
Sorry to say,he is speaking as a layman
He is right!!!!!
Wood must be treated....he’s right!!!!
They need to fill the blockholes with cement the buildings are hallow and that's why the buildings are collapsing. In Jamaica we go through hurricanes,floods,earthquakes and our building is not collapsing our building stands strong.
I thought he was going to suggest Bricks...Yes, they have more weight than cement blocks but they are made out of environmentallay friendly and readily available materials and are more aesthetically pleasing in my own opinion.
Right!
The issue with these buildings is they're built in stages. sometimes left open to the elements for years before completing
I'm always dazed by the boldness of the uninformed,the misinformed,and the outright blind.
Seriously Sir, What is your Calling? I mean where is this coming from, Boredom or what? 😡😡😡

@@ismailbolaji7107 Lol. Your reply gat me thinking "Imagine if God returns during this lockdown (from the christian perspective) Hmmm... 🤔”
Why so harsh?
BARWA Peter you can do better. Bring a constructive criticism than result to unnecessary insults.
Dr. blocks are not part of the building frame. Blocks are not the reason for building failure. A building fails due to so many factors. Partitions walls(Block walls) do not contribute to any building failure.
Hello Mr Sunday- of necessity I fell I must correct you. The reason why you have buildings callapsing is because they are using non engineered blocks and very steel reenforcement . Engineered blocks consists of coarse aggregate sand & Portland cement in the proper ratio. Then a portion is place in a mold under high pressure. This type of block is impervious to degredation caused by moisture, what you are seeing the use of inferior materials. As to the Chinese, they have mastered the building process, yes but a lot of their buildings do not last and many of their buildings do callapse. Yes they need to adapt more efficient techniques. Make no mistake quality buildings takes time-as foot note, it takes 28 days for concrete to cure.
I don't know what you guys are doing over there in Nigeria, but I am an Architect in Cameroon and I have been told by some engineers trained in Nigeria that your blocks are hollow and reinforcements are passed inside the blocks. but in reality in a proper post and lintel system the pillars and beams carry the load of the building and blocks or concrete masonry units should just serve as filling units for partitioning. so a building which has been properly designed with proper reinforcements and proper concrete should never collapse because of failures in cmu blocks
the real problem is the artisanal manner in which the blocks are fabricated and dried. but a cmu block which has been properly mixed and dried in a kiln will not suffer all the defects that this gentleman is talking about
This man has no common sense at all ooo, talk about cements mixing ratio and shut up.
We where waiting for you to suggest a better alternative and you only lamented like a little girl.
If houses are built like bridges then houses will never collapse.
Third mainland bridge is strong and will last because of proper cement mixing ratio and the foundation laid down.
Mr Businessman do your research well before coming out next time.
And for your information I will neither like nor share this garbage.!!!
Forget about what this man is saying he knows nothing about building the reason why buildings in nigeria collapses is because of the owners of the buildings they want to manage the money so they do low budget buildings even if the engineers tell them the implications they disagree I am I block producer 9 inches hollow blocks should not be produced more than 20 to 25 blocks per cement depending on the strength of the sand that is why we sometimes mix it stone dust another cause is the pillers and rods, foundation these are the main factors that should be put into consideration not this opinion he's bringing isreal is not nigeria niether is USA Africa our economy standard is not the same with thiers I'm proud of my country nigeria GOD bless you all
Did this man do any research before coming to vomit this rubbish he is talking here?
So what do you suggest
He talks trash
@@wilsonlawani8656Igbo people don't have respect but why? They like to insult
The cement blocks are not the only problem. We do not have a good sewer system; so the buildings are sitting on water that never completely dry out.
Cement block is not the problem. it is actually a sustainable material in Nigeria. but our problem is the quality of the cement block. No slump test or any form of test during manufacturing before going on site. it is suitable and good for our environment. Offsite construction like in the case of China is not sustainable for us in Nigeria. mass concrete or precast is not sustainable and its expensive for an average salary earner in Nigeria. cost of hiring a crane will kill the project. lifting the precast in place is going to be expensive for an average home owner in Nigeria. Cement block/ red bricks are still in use in the western. Timber construction cannot be used in Nigeria. the holes in the blocks are actually good for air exchange. what we need is a proper BUILDING CONTROL FROM THE GOVERNMENT. cement blocks is sustainable for our environment but can be improved and materials are available everywhere. we also have fungi here in Europe but what we need is a form of periodic maintenance.
High rise building or story building should have either steel frame or reinforced concrete frame in place. the cement blocks are supposed to be used for partitioning without carrying any load.
Has this man researched why the houses in the west are built using less inferior materials and the issues homeowners have and complain about in regards to quality of housing especially new built homes. Nothing beats a house built with quality cement and sand. Why do our people always follow the west. We have a different climate, different way of life and culture. Look at Spain which had a similar climate. THEY USE CEMENT / SAND HOUSES.
Those chinese building are not stronger my sir ,In china u will still find some building built with cement ....am not so sure where u got the idea ....i wasted my data.
Iv travelled far n wild and I've seen a lot of Chinese buildings collapse n I dont think its Nigerian contractors dat constructed d building so dats y I will not buy dis idea of urs.
Please do your research before posting videos. I am sure you don't live in a tree. Post videos with information that's is valid, not just post for the sack of making money.
The cement block is not supposed to carry any weight as Nigeria makes it to be. You construct the skeletal pillars with concrete, this carries the weight of the decking, then wall up with cement blocks. The civil engineers are responsible for poor cost cutting techniques.
Oh A big No to this!!! I really see nothing wrong with still building, with bricks. They are still being used in building in Nigeria, or Africa. So what! !. This style might be Outdated style elsewhere in the world, and in China. But it really doesn't matter. We are Us in Nigeria, we are not in competition. The earlier we start working on our mindsets to be just Us, instead of trying to be equitable to others, the faster we will come out from being disrespected by the world at large. Those 500 years old buildings in Europe you mentioned , are made out of bricks, what are you talking about? ?? Bricks is ancient technology, but durable. The pyramids and many other world artiquated buildings were erected out of bricks and they are still here with us today. AFRICANS, should just ARISE NOW , use Africa's own resources to BUILD the continent, irrespective of what the world, at large thinks. Africa, please maintain your own identity. Be yourselfand BE STRONG. .
I have traveled round the world, greatly involved in infrastructural development and can tell you sir, your advice is completely baseless. We still build with bricks in America, Europe, Dubai, Singapore and many other nations. So I don’t know what you’re talking about. The reason they use wood and dry wall in most American and European nations is because of temperature control, and lack of access to enough sand. How you build a house and what materials you use are what determines the strength and durability of the building
@Sunday Adelaja, it was the title of your video that caught my interest. Yes, surely there is need for alternatives to building construction technology in Nigeria, especially with our population of about 200 million Nigerians. We urgently need alternative materials that are cheaper and readily available. However, I would have given you a thumb up if your presentation was thoroughly researched. I was keenly looking forward to what good findings you had to offer and possible recommendations. It was more of problems for almost 11mins? Well, you tried your best.
I live in Brazil. they paint their houses anyhow. their building also collapses anyhow
Don't involve government on this matter . If you are going to involve government , then talk about issue of electricity first .
You talk too much and besides other countries tke care of their buildings because I live in Europe and travel a lot o stop criticizing Nigeria
you are not living in Nigeria; am sure you moved abroad for some reason
@@emipodro9685not because i live in Europe i travel to my country 3 times a year when the government of a country doesn't take care of the country how will the house now tell me how will house stand strong. The country am living they used woods and sheets rock to build their house and the inside sometimes has molds but not in Nigeria you see what i was expecting to said was they use too much sands than cement cuz my father build a huse since 1980 and the house is still standing cuz the foundation of the house rocks, gravel, cement and sands the rocks was broken mixed with sands , cement stones gravels, bricks for foundation so please stop criticizing Nigeria
With all due respect, you are spewing nonsense. This is from a Civil Engineer. Please stick to being a doctor.
Accepting other methods. It is not about cement blocks. Buildings collapse because it fails under loads that it was not designed to support. He is not competent to discuss this.
There's absolutely no point. He couldn't even mention what is in Vogue. He's just saying his mind... No technical backing at all....
He mentioned waterproof blocks
@@bishopwestcoast6705 what is waterproof block?
@@bishopwestcoast6705. Yeah but that water proof block is prepared by water proof cement .
He successfully said nothing.
As an architect I am ashame that an acclaimed P.hD holder is exposing his ignorance and lack of authority in the subject matter -cement, sand and additives blocks. A P.hd degree is a proof of someone ability in a specific knowledge area.
😂😂
I totally disagree with you sir, all what technology brought to us it look very good but not strong. Not last enough like holding days stuffs
Dr Sunday made his points but I think the waterproof blocks would be exorbitant here in Nigeria. It's time to start digging deep about waterproof blocks.
Gullible fellow, he has use water proof block to deceive you, is their anything like water proof block??? Is it water proof block they use in building bridges.??? Look up on Dubai modern documentaries, they use cement, lron rods, woods and sheets etc.
BUT....This man has no common sense at all ooo, talk about cements mixing ratio and shut up.
We where waiting for you to suggest a better alternative and you only lamented like a little girl.
If houses are built like bridges then houses will never collapse.
Third mainland bridge is strong and will last because of proper cement mixing ratio and the foundation laid down.
Mr Businessman do your research well before coming out next time.
And for your information I will neither like nor share this garbage.!!!
😂😂😂So true! Dr Sunday! If you talk about changing cement, they will say you are thinking like a White man.They will shout Naija for Life!
The only rationale for improving on cement blocks is to have lighter partioning in your building. Developed countries use timber partitions and sometimes glass. The main skeleton of your building is the frame (columns, beams and slabs). Every other element is basically a fill-in.
God bless you sir🙏🏽
Ouch! No, its quite unprofessional advice. Dont use layman perspective. Its my field of specialization. It seems you dont even know that there are different types of cements. The bridges across long rivers around the world, are you not surprised why they are built with cements and steel? Yet they are submerged in water for decades? Haba, How you build it is what matters and not necessarily the cement. So now, whats your solution sir?
Watch again. He is talking about houses not bridges. Waterproof blocks
@@bishopwestcoast6705 . You simply don't understand what the poster is saying. Adelaja is talking about waterproof blocks that withstand moisture a d fungi.
If there's a cement that can be used under water to build bridges( as the poster is said), it therefore means that there are certain types of cement that can be used for certain buildings.
Your argument is valid sir but I believe you could have suggested all technologies you knew.
That would have made your argument perfect.
Please tell us one skyscraper that was build in 5days in the world?.In Uk,they still building houses bricks.99% of the old houses in Europe and other places in the world are built with bricks or blocks.I believe the oldest block in Badagry,Nigeria is still standing.
What about the coloums, but we have houses more than 50years still standing.
@food forthought1 I've been abroad and does guys still have building from the 1900s they still look new. BTW Europeans and western countries know how to maintain their buildings
Apparently he knows little about what his about.
food forthought1 everything damn single thing is not about scam. This is clearly an issue of standard. This is no enforced standard for buildings.
My question for you is that.. what did you use to build your own house you are living.. or you haven’t build your own house..
I will be happy for you to reply..
Thank you my brother white hair does not equal wiseness
