@@henryrollins9177 yes, you are right the brick is required to be completely dried. during the selection process of the bricks the masons placed the samples in a bucket of water to check their ability to retain water and selected accordingly. the most plausible explanation to this is that the brick absorbs the water in the rich cement mortar which increases the adhesion between the two materials. As they complete 3 concentric rows they put cement mortar on top and spray it with water (9:37) so the cement mortar in the joint does not crack since the brick has partly absorbed the water. It is a mix of this and the pure form geometry of the dome which in turn helps distribute the forces evenly across the assembly.

Well, if you can't eyeball it, you can use the string. Fix the string to the center of the room on the floor, bring the nail on the string up to the layer you're working on, hold the brick in place with one hand and score it in an arc with the nail on the string. Then you can chip the part you don't need off.

I had attended a workshop where we had to build two types of domes, one on a circular base and the other on a square base with pendentives at the 4 corners( to get a circular ring). For the latter, we needed a level tube to maintain the levels on all 4 corners, and most of us got it wrong. It's astounding to see these guys do it without any level instrument. Awesome!

@smokerjoe5231 3 жыл бұрын

@Roderick storey Except in the foothills of the Himalayas, India is not famous for its snowfall. BTW, rooftops are different there. As for rain, it's a problem if the roof is flat. Here, it's a dome not a pool. Water flows naturally outside. A dome (or an arch) can't collapse. Its weakest point are the walls that take all the forces. Moreover, this method of construction is ancestral. If it didn't work, don't you think they would have done it differently? So strength for what? ==> For their needs. That's obviously enough

Id love to try seeing a couple of these done, challenging maybe but it looks pretty simple once its set out properly 👌 Some of the cuts could be measured and cut to create a better wedge but as long as its joints are full, an arch is self supporting. I built a voussoir arch and as soon as i pointed it i stood up on top of it to prove its stregnth. It was in my back gerden built on the ground and not on an actual structure.

@zerg9523 3 жыл бұрын

Okay, watching the process with a keen eye i picked up a few things... 1, Before the first ring is complete, the corners appear to be built as independent arches, so those need no real assistance to be supported. (6:30) 2, Once the first ring has been completed, brick geometry then becomes far more important. (7:40) 3, The cement mix is also critical, it needs to be very adhesive, must harden reasonably quickly and not shrink too much when dry. (8:30) 4, I suspect the cement shrinking is part of the reason they render the top immediately while also spraying to keep it moist. (9:30) So why does it not fall in? Put simply, physics... The reason a single brick doesn’t fall in when being placed is the cements adhesion... The reason a whole ring doesn’t fall in once the cement is dry is because of geometry, the ring as a whole does not fit through the hole below it.

What gets me is how the building supports the thrust forces created by an arch or dome. I see that the ring beam that holds the dome is made of concrete, while the rest of the building appears to be normal structural brick. So I am assuming the ring beam is rebar reinforced concrete, and that can handle the thrust force. That means that technically, while the dome is an ancient building method, using it in this way is only possible in the modern day. Previously, the building would've needed massive walls to support the dome.

Brilliant work by very skilled tradesman. Lots of comments about how the bricks stay in place as they are being laid ! It's a combination of many things but the key here is very dry porous bricks and wet sticky mortar. If you laid this brick normally on a wall and waited 30 seconds or a minute and tried to pick it up you would struggle as it would be slightly stuck. As the dome goes up its shape and the forces take care of the rest. I really want to build one now, I would love to spend a week with these guys.

The west (assuming you are from the west) has strayed too far and slowly India too is drifting that way... luckily we still have some master masons who might be the last ray of hope and the custodians of invaluable traditional knowledge, that is mind-bending! What is really stroke-worthy is the fact that houses in the west are these days made like matchboxes with flimsy timber that will go up in smoke in a jiffy. Soooooo much needs to be done to keep it protected from the elements and termites and bugs and towards thermal insulation. They result in a very heavy Carbon footprint. Conversely, these traditionally build homes and structures are sustainable and eco-friendly. This might come across as an East v/s West run down but is only intended to say that we, in India need to cradle and protect this knowledge before it is wiped out.

For each course (ring) of brick the wet mortar has enough adhesive strength to hold the bricks in place until the ring is complete. At that point, each brick course is acting as a compression ring with the forces pushing outward. The lateral forces are strong enough to overcome the gravity load. When the entire dome is complete, the rings act together and the forces are distributed in all directions. Very impressive and economical to build, although I'm a little surprised that they rely on running bond for the brickwork - headers would make the whole thing easier to construct.

I just can't understand how would bricks stick to the cement mix without a vertical support, at least till it dries? 🤔. If one circle is completed, may b bricks wouldn't have enough space to dislocate from each other but till that circle completes only thing which holds bricks are wet cement mortar.

@paullangford8179 3 жыл бұрын

The mortar has to be just the right mixture of stickiness and stiffness. The bricks need a slightly rough surface (for example made with sand in them). The mortar must cure properly, NOT dry out, otherwise it crumbles. I have seen an arch made using concrete blocks, but it was not very wide.

These brick are light compared others and also very dry. As soon as you put the mortar on, it starts to pull out moisture so you must be fast when placing the brick. It also creates a suction, like when you step in thick mud with your shoes on. Plus once you complete a row, it then has binding strength. The type and consistency of the mortar is important also depending on joint size. There are other factors I'm sure, but the main thing is that it works. The ones done in Mexico look like they're done entirely by eye, no tape, no strings, nothing, just put em up. This is what amazes me.

H DB okay, you’re saying that buildings collapse. Yet you have no real reason to give why these would? Other than some gut feeling that it’s not strong enough? I just think that you don’t understand how strong a dome like this can be and so you try and act like you know more than you do about a bunch of unrelated stuff.

For the people who wonder about the strength of the roof. Its not as simple as seen in the video. All the bricks are places at very precise angles making a low ark dome. This structure is in use since long in ancient buildings. Very stable and strong. Dome shape structures are very common in Indian architecture. It is modified form of same technique.
