Red Mud Brick using Lime and Coir Fibre

Abstract

In India, about 1 Crore tons of red mud residues are being generated per year, posing serious environmental problems. It is possible to utilize neutralized red mud in construction practice. Coir fiber has tensile strength, ability to resist cracking, spalling and increases the durability. Laterite soil needs minimum stabilization and it is durable, reduces CO2 emission and it is a good thermal insulator. Stabilization of soil becomes essential to attain adequate compression strength. In this research project coir fiber, red mud along with lime is used as stabilizers in laterite soil for improving the strength, durability of brick and thus to provide affordable housing. By implementing this technique in effective manner, bricks can increase the lifetime of structures, reduce moisture and used as an alternative building material.
