The Romans used pozzolana cement from Pozzuoli, Italy near Mt. Vesuvius to build the Appian Way, Roman baths, the Coliseum and Pantheon in Rome, and the Pont du Gard aqueduct in south France. They used lime as a cementitious material. Pliny reported a mortar mixture of 1 part lime to 4 parts sand. Vitruvius reported a 2 parts pozzolana to 1 part lime. Concrete was originally developed by the ancient Romans, whose building techniques were lost with the fall of the empire and wasn’t reinvented until 1824 when an Englishman named Joseph Aspdin discovered Portland cement by burning finely ground chalk and clay in a kiln until the carbon dioxide was removed.
Dad was a builder of commercial and industrial buildings. When he had a job where the mixers could not get in, I got drafted to “operate” a wheel barrow. Seeing the whole process presented here in order, and with details, was extremely interesting. I will look at more of your presentations.
Thank you very much and i am glad you liked this content i will create another video about construction, cement, etc etc in my next creation stay tune for more like this
I worked for 30 years in a foundry that made the wear parts for the machines that manufacture cement. There are a great many more details in this process that were not covered in this video but what was presented was fairly accurate. I suppose I am biased due to my occupational involvement but I think this video spent way more time discussing the simple process of mixing concrete than it did the very detailed and interesting process of mining, crushing, calcining, grinding and particle size and Blaine control of making the actual cement.
Cement mixtures should always be handled in a manner that eliminates prolonged exposure to the skin, and mucus membranes. Concrete and cement can cause serious burns and infections of the skin if not neutralized immediately. Cement residue will not simply rinse off the skin with water. the chemicals in the mixtures are still active and are absorbed into the skin. the burning chemicals can be easily neutralized by rinsing the affected areas of skin with vinegar. Only seasoned veteran cement finishers and laborers who work with concrete on a daily basis will have a bottle of vinegar always at hand.
It's longevity is the best attribute . For highways , if formulated correctly , superior . Sections of U.S. 40 between Sacramento and Auburn Ca. were laid in 1929-30 and are in near perfect condition . Traffic from Sacramento to Reno and points east , including heavy trucks used it from 1930-1959 when I-80 was opened , and carries traffic including trucks since '59 .
i was inside such oven changing a section with some guys,, i even had to be inside while it was turning, we walked to the end and look down in that big pit, somthing i will never forget..
Cement (the Adhesive) manufacture needs lots of Heat to make. Yes, there is underwater Concrete, and concrete which can be poured/cured in freezing weather.. You can also add gravel, stones, & rebar etc. to concrete..
I love using cement in making an statue sculpturing because it doesn't fall off in many, many years, it stays together so long as the proper mixing & consistency are applied
My father told me how in his apprenticeship he learnt about different types of mortar, concrete and how these are made in ratios! I now find it interesting at age 50. He did his apprenticeship in Yugoslavia and then moved to Austria to work. He was a site foreman! Then my parents moved to Australia! Cheers ❤
I am so passionate about the manufacturing of cement, how I wish I have what it takes to go into manufacturing cement, I will have love to own a cement producing company, pls I need a mentor on this roll.
The thing I find most interesting is the weight of it. I used to deliver truckloads of bagged cement. It only takes about 12 pallets to get your gross weight up to 79,000 lbs.
Boy…… that took me back to my carpentry apprenticeship in 1973!!! We mixed all our own concrete in an on-site mixer…..which produced one barrow load of concrete!!! Into the mixer went a bucket of water, five shovels of aggregate, then two shovels of cement!!! We let it mix…. Then added more aggregate to stiffen the mix!!! We used this method for foundations, slabs and concrete walls!!! If pouring a foundation and the concrete stopped flowing….. the boss would ask for a pea soup mix, which was basically water and cement, to unblock the jamb concrete!!! 1500 degrees Celsius to make cement….. don’t think solar and wind power can generate that amount of heat!!!! Fossil fuels forever!!!! Regards Ian 👨🎤🇳🇿👍🍸🍸
Too often people forget the most important part of laying concrete, the curing. Keep it covered and wet for a week and it will be much harder and durable.
I seem to remember we used to add washing up liquid to our water when mixing cement . It acted as a good plasticiser when plastering walls. I think an additive is now marketed instead.
The reason that washing up liquid is a really bad idea in cement products (usually mortar rather than concrete) is that it has a very high salt content, and this can lead to efflourescence in brickwork or other adjacent masonry. This appears as white deposits on the surface, and is very unsightly, and ultimately damaging to the masonry. The admixes used in place of detergents avoid this issue.
They've stole "how it is made" and stuck a voice over on it. It's diabolical. It's taking something perfectly good. Trying to make it their own. And convincing themselves they've somehow achieved followers and likes for their own work. It's everywhere bro. Leaches
Most impressiv is how old old this is. 2000 years ago, roman empire did make cement which was usefull under water. Hagia Sofia have survived many earthquackes and it repair itself. Old concrete is better than new one. That is very impressiv.
Thanks! Ive been in construction for 40yrs and didnt know some of the fine points of the substance i used all the time. I heard that cement making was the biggest heat producer for global warming.
I have worked with cement for large parts of my life. Everything from receiving and reselling from dealers, to building houses and have always wondered how cement is made. Thank you for a good review of the process. It was then that the cement bags weighed 50 kg and I weighed 63 kg and I was able to move 250 kg in one single lift. 🤣😂
The slower the curing period, the better and that includes lots of moisture. If concrete sets too fast or false sets and shrinks it can be a really costly error. In a process, some slabs are immersed in liquid to cure very slowly. Cement is relatively impervious to water, so it takes a lot of water to saturate the cement and get the optimum strength from it. The clinkers can be stored outside and they resist water to the point that they are unaffected by it. It isn’t until they have been pulverized that they begin to accept water. Our current world would be vastly different without cement.
We have plenty of raw materials here in Candoni, Negros Occidental, but, we don't have investors for Cement Factory. All Nations really needs a Cement Factory.
To make an attractive and less jarring finish leave the concrete to set (takes a few hours depending on temperature) then brush the surface gently while washing with plenty of water. It will expose the aggregate.
You can't just add water willy nilly. The strength of the concrete is carefully calculated. The amount of cement to water was part of this calculation and by adding extra water on site to make it more usable will weaken the concrete which could be critical.
I'm surprised there is no mention of the angularity required of the aggregates. It is required the sand and stone have sharp angles. An on-site engineer can reject a batch if the aggregate is not angular enough. It is said we will soon face a shortage of workable sand. You look at the desert and think that is crazy but windblown sand is round and river sand is angular. We need the river sand. Great video. I was interested in the kiln process. "How did anyone ever figure out you had to cook the parts for the best results?", I ask myself. Granted chemists know how and why but someone figured it out before modern chemistry.
Concrete is the preferred material for city streets in some parts of the USA. In other places, even at similar latitudes, streets are paved with asphalt. What are the respective cost, utility, and longevity factors? I presume that asphalt is cheaper to apply or repair, but wears faster and does not survive many winters that require lots of salt to melt snow. Concrete may last forever, but it is cast in blocks that, over the years, tilt or buckle, making a ride rather bumpy, and whose replacement may be expensive. Am I naive or mistaken?

But kids that grew up next to a construction area would have been able to figure it out by themselves!

That is correct

Did the unsavory criminal elements in ancient Rome dump bodies as filler prior the pour too?
It's also doubtful modern cement/concrete will last as long a roman variety. The Romans were also able to pore their concrete underwater.

It’s amazing how concrete can be finished in so many different ways. Smooth to rough to different colours to different textures
Hello, how are you? It's fascinating how with this cement you can build incredible things and beautiful buildings.
What's even more amazing is how he says it can finished "after" the curing process😂😂😂
i was inside such oven changing a section with some guys,, i even had to be inside while it was turning, we walked to the end and look down in that big pit, somthing i will never forget..
that is awesome and i little scary
Wow! Such basic raw material to produce this super product.
Thanks 😮
I love the level of industrial activity involved in this particular process.
I'm excited to share this video with my civil students.
Thank you for sharing god bless
why not show all the students?
Brilliant video need more like this
That was a lot of info in not a lot of time. Just how I like it. Well done.
How did they do it back in the 1930's? We know this technology didn't exist back then.
How did the Roman Empire do it, they wouldn't have had the technology that we have today
Now THAT was amazing...........................
Thats what she said!😮

It was a good presentation except you left out the chemical reaction that would explain how the water causes the cement to harden.
Very informative content but gorget to explain various types of the cement and differences in their properties.
Discussing cement manufacture using rotary kilns and then shows a graphic of a Maertz

I see this is a lot more complex than simply mixing a bag of cement to throw on the ground
Yes indeed
I think it’s fascinating watching how cement is made but I think some people can make it from scratch too
Nice video! I learned some things, very interesting.
Thank you Very Much i'am glad you liked it
Reminds me on how plumbus are made (rick and morty). All "how it works" videos do sound a bit the same😂. Thank you for uploading, it is interesting.😊
great to see how it's made
Cement and concrete are the foundations of most of the world. No pun intended.
why say something so dumb then?
I've always wondered how concrete is made under water like bridge columns in a river.... now the phenomenon of hydraulic cement gives me the answer...
The three absolutes of concrete: It always hardens, it always cracks, no one will ever steal it.
leave a few bags outside your house
great video thank youuuuuu
Thank you god blesd
Cement is great because it's an important part of concrete. Concrete is awesome because it has rocks in it.
Loved it!

Adding a small amount of sugar makes it that hard that you need an pneumatic hammer to break it.
No matter what you do , efflorescence occurs . Eventually it does disappear , but this does take a long time
