Water curing that is. It dries from the outside but not from the inside, escaping moisture causes the concrete to crack. Water curing is the solution and it also gives the concrete to reach its maximum strength

I’m a brick layer… lime crumbles a lot so more like in the cement mix would make it weaker. That’s why we stopped using lime and went with soft sand instead cause soft sand is way stronger.. we still use lime when the customer asks for it if they want a type of style wall
Depends on your climate.. lime mortar is autogenous.. self-healing..wet or damp climates are deleterious to the mortar..although I got taught the mortar is just for holding the bricks apart..the strength is in the product and bonding and gravity
Good said. How they usually say about Roman concrete... Self healing and so on...but it's brittle because of limestone, it couldn't support the buildings we build now, like skyscrapers. In this video, they showed a hack for building easier and faster, but nothing about the longevity. No need to reinvent the bicycle, supports and scaffolding are more than useful. 2-3+ more weeks for traditional construction is justified by 20-30 years more longevity
I don't know about lime Mortar mix. In my region I've seen too many chimneys and various walls crumbling and requiring attention or demolition in last couple decades . Maybe shortage of materials due to austerity measures during the war plays a role but I'm suspecting it's the chemistry due to the 80% increase in atmospheric CO2 . So a relatively dry region might be okay but a damper more foggy higher humidity region would be a problem on account of higher carbonic acid levels. Also feared to be a problem for shellfish.

NOPE, the secret is bone dry bricks!! I saw the video in spanish where the workers said that there was nothing special to the mortar but that it was extremely crucial to have dry dry dry bricks, no moisture whatsoever 😊
That doesn't surprise me, the individual bricks have to just hold themselves up until they get around to a complete ring. Then the ring itself helps to keep it in place.
Stupid comment, if you are under een unsupported brick roof, then in doesn't matter wheter you stand in there or a modern home which is build with supports.
The arch is Sumerian. So is the ceramic, the sun-dried brick (forming the inside of Ziggurats) and kiln-dried brick (the outer layer) as well as irrigation (irrigation was also found in China thousands of years ago).
Fun fact The Arch on the Dome was invented by the Romans, which was in my opinion was a more improved architecture which was continued from Greek architecture .
A keystone ( Or Capstone) is the wedge-shaped stone at the apex of a masonry arch or typically round-shaped one at the apex of a vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight.
This Method Is Iranian !!! In Iran We have Dome, temple of Fire, Palace and bazaar that are still healthy after 2000 years !!! And it is part of Iranian architecture, which is called Chahar Taq The Largest Taq is "Taq Kasra" in Baghdad in Iraq which Built By Sassanians!! Almost 50% of the Building is still intact !!
I see a few comments about the string, yes we know about guide strings, but the speaker is rite about the string they are using it to keep the bricks in place while adding more , how u ask? That brick at the end of the string is putting pressure on the string so now the part of the string against the bricks thats being suspended will stay up because of that pressure......ur welcome
That holds together not because of the mortar it is because it was lock as an arc they push each other down and they wont fall because it was an arc.just imagine pushing a a curve rod into a pipe bulging upward.how would it fit?
I have known of brick domes used to cure brick. They failed due to mortor cracking. Now most brick manufactors use long barns and rail road style track systems. Some brick is very brittle. Adobe brick has the highest thermal mass index. Key stone construction fails due to lack of horizontal pressure. Geodesic domes have the highest survivability of all structures.
Brick domes are fairly common in Mexico. I didn't know they were that amazing until TH-cam started pointing it out to me. Since then, I've seen videos that make claims that these domes are structurally sound and that they lower the A/C's energy requirements. If you have a link to an architect who has actually studied these domes or a scientific paper, please share it here
I disagree. My father taught me to soak the bricks for an hour or so before using them. That’s what he was taught so one day we tried doing some garden brick walls with small arches. The section of soaked bricks took about 50% longer to setup against the dry bricks. After a few hours it took quite a bit more force to dislodge a brick. Is this in accordance with the scientific method? No. But 3+ generations of my family has done it that way. Goes for cinder blocks as well.

The ropes are not to suspend the bricks, they are used for alignment and the secret is not only the ratio, it is also the angle of attack of the initial bricks and inclination of the ones that follow
Actually, the use of arches originated in the Roman Empire and was further developed during the Byzantine era. The video seems to have this incorrect. These empires were pioneers in this architectural innovation, which has influenced building techniques for centuries.
Brick is the ultimate building material. Termites hate it., it doesn't rot, it's a good insulator, never really needs cleaning, is recyclable, and if done properly it's beautiful.
These Brickys are genius....so much talent to do this and do it well so that the whole building is pleasing to your eyes....it's very hard to get right..😲🙂
One of those 'in-process' structures shown...is the famous "Catalan Dome". The engineering physics of that dome creates buildings of incredible, self-supporting strength!
That technique where you build 4 arches out from each corner relies on the brick sucking the moisture from the wet mix of cement. Its the suck that keeps it in place while the course is being laid. Those guys work really quickly to get each course done before the sucking stops. Once the course is in place then it becomes an arch in its own right and supports itself.
Respect to all the masons in the world, our most beautiful architecture is with brick and stone. Even the simplest wall is still something worth appreciating once you see the effort and skill required to do that.
Arches were first used in the 2nd millennium BC in Mesopotamia, but the technique was mastered by the Ancient Romans who used arches in bridges, aqueducts and even in domestic buildings.
If you have bricks which take up the water from the mortar the mortar will fail. The mortar is not drying, like clay, is undergoes a chemical reaction where it is essential to have the right mix of water and cement. Excess water is not a problem but too little is.
It isnt one point rwo ratio . It's one to two ratio . Thats one part cement to two parts lime . What isn' mentioned in the mix is how many parts sand. Normally it would be three parts sand (2 parts sand would be stickyer) then add "warder/water to the consistancy desired (the way you like your mashed pataders) This makes a very "STICKY" mix to hold things togather. Its a weak mix as lime weakens the mix. Lime is used as a "plasticiser" so the mortar is easy to work ( a creamy texture normally) and less sandy. Lime is help the mason work comfortaby. With arch work your sticky mix does act like a glue seamingly working against gravity. I've been doing masonry consistantly since 1978 and still at it. Hope this helps all you whippersnappers out there
I was gonna say bruh like some bricks are actually cut at an angle to make arches have that much more support. It could hold even without mortar (if you built it ON something and then took that floor away), the mortar is just there to seal it and make SURE it stays.
Cement shouldn't dry fast. It takes time to harden perfectly. When bricks absorb the water, the cement next to it has no chance to harden. This dry cement doesn't stick well to the bricks. You can take such a construction apart with you bare hands.
The line is the glue limestone is baked until it reaches a certain temperature then it is ground up into a fine powder that is what cement is limestone

There's a huge railway bridge made with such hanging bricks near my house. Before this, i always used to wonder why doesn't the brick bridge collapse when the heavy train passes over it.
Look at mortor mixes for laid baring mortor vs mixes with less tinsle strenth. Load baring mortor has less lime. I'd rather use ropes or forms then mortor with less tensle strength. The arch may be shelve supporting when finished but the mortor is subject the compression in the arch as well. If it gives out so does the arch.
Just make sure on a cold day, i repeat a cold day that the mortor has set. Did a cooling tower that way. Only problem was when they tried to go higher on a cold morning. Because it was cold the mortor hadn't set and it all came down. I know an arch is not the same as a cooling tower but the mortor and it setting is crucial.
No its how the bricks are layed. In sections. The dome is done for that reason. Notice theres never a flat celing. Also that tiny string does not hold up a brick, let alone several. Its a guild
These brick ceilings are visually some of the coolest ceilings I've ever seen but, without any kind of rebar how well do they hold up with earthquakes?
Mortar is lime, the term should be aggregate and lime.... And without mortar, these can also be unbreakable with only sand filling, if brick edges are set properly....
Sadly, you don't see these construction methods being used anymore in new construction in Europe. It's only if older buildings or buildings worthy of conservation.
@@seanloy1110 Generally the bricks shown in the video appear to be quite soft and porous - they're certainly not engineering bricks - so they will need protecting from the elements even if a waterproof mortar was used.

Generally, one doesn't want mortar to dry. If it dries before it hardens, it could compromise the integrity of the mortar.
Mortar is lime, the term should be aggregate and lime.... And without mortar, these can also be unbreakable with only sand filling, if brick edges are set properly....
Sadly, you don't see these construction methods being used anymore in new construction in Europe. It's only if older buildings or buildings worthy of conservation.
I doubt very much if the mortar is made only from lime and cement - you'll need plenty of sand in there too.
lol 😂
Mabey even some waterproofer do you think ….?
@@seanloy1110 Generally the bricks shown in the video appear to be quite soft and porous - they're certainly not engineering bricks - so they will need protecting from the elements even if a waterproof mortar was used.
G E N I U S ! A true brick mason is worth his weight in gold !
Is it safe during earthquakes?
Until an earthquake comes along..............
Read somewhere that limestone is self healing. If I remember correctly, its the reason the Coloseum of Rome still stands.
(superdry) woodbricks wood be an interesting alternativ, too. They would expand in wet air, strengthening the whole structure, too.
"Is even less likely to col......." it was at this moment he knew he fuc@ked up.
The secret is the dome structure. At a set angle the weight pushes out and down evenly.
