Mud bricks are being widely accepted for building homes that are eco-friendly as well as cool during immense heat.
There is an urgent need to address the great challenges of our times: climate change, resource depletion, pollution, and global warming. These issues are all accelerating rapidly, and all have strong links with the building industry.
Sunny Nelson is a 33-year-old former Merchant Navy officer, he decided to take retirement from his job to make a living from agriculture in his home town. He decided to build a house that is not just eco-friendly but can also reduce their monthly electricity bill of coolers. After quite a research he decided to build a house entirely out of the mud. He used laterite to build the exterior of his home, for the roof, he chose weather-resistant clay tiles. The walls of Sunny’s home are plastered with mud. In the kitchen, Sunny limited the usage of timber or any other kind of wood for making cupboards and shelves. The construction began in June 2019 and was completed by February 2020. Even though the house is equipped with two fans they rarely feel the need of using it.
Mud is one such construction material that is borrowed from the earth and can be replaced after use. It requires little or no processing. All the energy inputs required for the process are directly or indirectly taken from Earth. It is cheap and has thermal and acoustic values. Basic mud bricks are made by mixing earth with water, placing the mixture into molds, and drying the bricks in the open air. Straw or other fibers that are strong in tension are often added to the bricks to help reduce cracking. Mud bricks are joined with a mud mortar and can be used to build walls, vaults, and domes. Mud structures can be made strong enough to bear a load of a couple of storeys at least, but are really low on its insulation capabilities unless mixed with other ingredients.
