Ancient method of traditional lime mixture is best for this method of construction compared to cement lifetime is also longer in traditional method! Sister but you guys are done a great job my favourite part of you're videos are rammed earth wall🤠👍

Egyptian architecture Hasan Fathy describes another traditional domes in his book “ Gourna; a tale of two villages “ he used to build the roofs of the houses in his project in 1940s using ancient Egyptian methods and only using natural materials without cement. His buildings are still there and preserved.

Kudos to you madam.. When i planned to construct home in my village, i searched for alternative roofs, and i am interested in this type of roof.. But no mason is ready to do this in my village, they laughed at me and said, it wont last a year without iron😐.. Another one is madras roofing, which needs more timber.. So i ended up with steel and concrete one

The concrete beam is structurally required for the vault to work. Also it is not true that it is built without steel, you can see it on the plan at 4:55 and you can see rebar sticking out of the beam. The roof will stand up as long as the rebar in the concrete beam won’t rust. That’s why the dome doesn’t have a longer lifespan than a standard reinforced concrete ceiling. The lifespan of the ceiling is the biggest factor in sustainability, if it was really built without steel the brick vault would have the potential to stand for a thousand years, but not when it’s built like shown in the video. There are ways to solve this problem

[@farmaanandaa]

Do share your solutions. It will help the viewers on this channel. Thank you.

[@7_21_44]

@@farmaanandaa There are two ways I can think of that could eliminate the use of reinforced concrete: 1. The first solution would be very high in cost and material usage. You would have to build massive abutments/thicker walls to catch the thrust force coming from the vault. 2. The second solution would work with thinner walls but would impact the look of the room. You would have to use steel reinforcement spanning across the room to secure the walls in place. This way, you would convert the thrust force coming from the vault into tension, which would be carried by the steel. The key is to make the steel accessible so you can maintain it when it rusts or even replace it. This is how vaults above ground (without earth pressure supporting the structure) were built for centuries (before the introduction of reinforced concrete). By the way, I don’t want to criticize the craftsmanship of the bricklayers; they did a beautiful job, which is forgotten in many places around the world. This bothers me even more because I know that it won’t last longer than the reinforced concrete beam that it sits on.

Beautiful! just one suggestion, instead of cement use slaked lime, (When quick lime reacts with water it produces lime water or slaked lime. CaO + H2O → Ca(OH)2 The more you keep it dipped under water like 15 to 30 days its bonding properties increases many fold and old Fort walls and roofs are made this way, still standing today best example of test of time. And its more eco/environmental friendly Thanks

[@farmaanandaa]

You are absolutely right. And we have used slated lime in most of the construction. We have a lime tank built on site. However, the Rohtak domes artisans do not work with Lime because it takes time to set.

[@a.s.562]

Thanks for introducing this magnificent technique! How many layers of bricks shoud be installed at once, without falling/sliding?

[@farmaanandaa]

The masons know how to do it. Pls contact them. It's not easy to replicate this technique.

[@yatharthagarwal6161]

Hello ma’am it’s really inspiring what you’re doing we definitely need more people like you. I also have a similar dream like yours and for that right now I’m learning/understanding natural building techniques here in Auroville. I think you have used cement mortar in the dome making if yes then why didn’t you use lime mortar? And Rohtak dome and vaults can be done on rammed earth walls also?

[@farmaanandaa]

Lime takes a while to set and will not be able to hold the bricks in place. We would have loved to make it in lime mortar, but Narayanji does not make these domes with lime mortar

[@BISWARANJANBHATRA]

These roofs usually have one central point where the fan hook is put. Lights have to be put on the walls.

[@nayan4121]

What is the ratio os mortar. Can I make it by Lime mortar

[@farmaanandaa]

The artisans dont make it with lime mortar .. we asked them. This is because it set very slowly, but they need quicker setting for continuous building of the dome

[@thedarkknight4243]

Which is better? Wooden Roof, Concrete flat Roof or Metal frame roof on the basis of strength, weight, water-proofing, insulation and other aspects? Would like a Structural Engineer's perspective. Also, can Ram-Earth and/or Earth-Bag walls hold a concrete flat roof?

[@farmaanandaa]

I am not a structural engineer, so won't comment on that. Yes, rammed earth walls can hold a concrete flat roof, as done in our FIller Slab roof.

It’s wonder job,so you had rammed earth walls and you have used concrete structure on top of them to support the Catalan dome ?

[@farmaanandaa]

Yes a ring beam.

[@dinkaboutit4228]

Most rammed earth walls have a concrete "cap". It serves the same purpose as the top plate on a stick frame structure, and it gives you an easy way to install the lag bolts that will hold the roof on, you just insert them into the wet concrete and try to make sure that they're standing up straight.

@@VisharadSaxena It's very difficult to do it practically all of sudden. What ma'am has done is minimum use of cement. Probably they will reduce use of cement in next project. 100% natural construction is very much difficult and impractical in today's time. But they are putting their best efforts.

[@VisharadSaxena]

@@pragneshparekh7652 thanks. To clarify - I had retired some three years back and am researching independently about climate change. It is a major and real problem, and yes, we are the reason. I have an organic farm. Is it healthy and better? Yes. Is it sustainable? No. Most of the things we do everyday, all of us, have negative impact. I am no judge because I am part of the problem. But, we are the solutions too. I will not appreciate my fault when I know it is wrong. I watch Aanandaa videos around 45 to 60 minutes everyday as I learn from them and trying to shift my organic farm into a permaculture farm. I will still watch their videos. I will visit them (if they allow after my anger :D) and learn more on how they do thousands of things better than me and where I can do things differently. My concern is tagging a concrete roof to the topic of sustainable housing because it is not. Absolutely not. Cement is a read bad thing. If one has to use (I have it in my place) I would not call it sustainable. One can be emotional about wars, politics, movies, so can one be about climate change. I would want all to be emotional about climate change because it is a bigger problem than anything else. That is why my outburst. I am not usually like this, sorry. And to add, sustainable building materials are present everywhere, older than current ones, cheaper too, NOT TOUGH TO MAKE. Probably, much easier than making the actual "choice" of building using natural materials. We can switch 100% not in much time. Maybe our current ways of life make it tough to make that choice. I still will look up to them for number of other things. 90% of my watched history is theirs. :D

@@farmaanandaa Makes sense

[@vinaytalluri]

I was under the impression that you avoided Cement totally, but I see again there is usage of cement for pillars, beams, ceiling. So you compromised on experimenting it with 100% effort. Pch I am quite upset with this.

[@farmaanandaa]

We never gave the impression that we have avoided cement completely. We have only minimised its use. Always choosibg an alternative wherever it wasn't absolutely necessary. We have probably used 10% of the cement the house would have normally used. Thats not something to be upset about. Its something to celebrate, as most constructions cannot even achieve that.

[@VisharadSaxena]

Please avoid using cement, these bricks and RCC. This is NOT SUSTAINABLE. I know it would be better than many many structures around. But, attaching the sustainable to anything cement is incorrect. I understand that sometimes you have to use it and sometimes we cannot avoid, but in that case, please do not promote it as 'sustainable'. I am hurt not because you used it, I know you guys must use it very little. But, understand cement is one of the leading causes of climate change. The word sustainable is INCORRECT in every sense to be used with it.

[@farmaanandaa]

Pls don't get emotional. Sustainability is a journey not a destination. If you make it very difficult for people to start this journey, no one will change. We must embrace small steps and not allow great to be the enemy of good. This is a sustainable roof options given its life span and material usage. We must support every attempt at using less of cement or other unsustainable materials.

[@VisharadSaxena]

@@farmaanandaa sorry, there are far better and sustainable alternates to roofing than cement. I understand, it is a journey but a few factors are a big no. CEMENT SHALL NEVER BE TERMED SUSTAINABLE, THIS IS MY PROBLEM. AND IT IS AN EMOTIONAL ISSUE FOR ME. Cement is a big driver to climate change, like a big big one. Calling it sustainable can never be and shall not be justified. I know you use it sometimes when you do not find alternate. I understand that. But, please understand my point. This was a roofing structure by choice and calling it sustainable is my only problem. In terms of longevity as well, natural structures built before cement still stand tall across the world. Cement has a limited lifespan.
