As the seventh largest country in the world and second most populous, India is known for its rich historical culture, but there are also people struggling with poverty. Urbanization has become a problem for some and has caused a 73.6 million housing shortage.
Although a solution to this are traditional mud houses (houses made of a blend of clay, sand, and silt), there are still a lot of concerns. TU Delft Global Research Fellowship’s civil engineer, Yask Kulshreshtha is looking to tackle these problems.
How to reduce costs?
The first concern was that these houses weren’t affordable enough. Shipping of the materials makes up for 90% of the costs, said Kulshreshta. He aims to fix this by getting resources that can be obtained locally. Through this, it’ll be cheaper and faster to get the needed materials for building.
Second, he took into consideration the design of these houses. He wanted to encourage people to build mud houses and one of the factors that could affect that is how it looks. With innovative and appealing architecture, people will surely want to build more of these traditional houses.
Material for houses has to be very durable
Lastly, what troubled him was the durability of the materials. While the houses were sturdy enough to stand tall, they lacked water resistance and that was a huge problem. He believed it was more of a technical issue with the material itself. So he is now researching with his team, a material that was biological and water-resistant. Yask Kulshreshtha from the TU Delft thought of adding starch or cowpats as a way of strengthening the traditional mix of these materials.
He studies this in his lab at micro-scale to avoid the waste of materials. One of the endearing things about his research his he does not plan to patent his local recipe once it is finished. “Usually, families build their own houses, or they employ a local building contractor. Everything is local. They would not want to pay someone from outside of the village who is earning money from their house because of a patent”, says Kulshreshta.
