Utilization of Black Cotton Soil in Manufacturing of Bricks

Brick is used to make the walls, pavements and other elements in masonry construction. Black cotton soil has very low bearing capacity, high swelling and shrinkage characteristics due to which in construction site, replacement of Black cotton soil is done with any other soil which has better geotechnical characteristics, hence it can be presumed and that can be partially used for manufacturing of bricks. Here in this paper an experiment has been conducted to replace the red mud to brick by 95% of Black cotton soil, 2.5% Rice husk ash and 2.5% coal powder. Certain test were conducted and we obtained and the strength of bricks which are produced using black cotton soil are expected to be much greater when compared to the normal bricks as the soil is having good properties such as adhesion , bonding etc. Since the cost of production in bricks are also very less compared to the other bricks, the bricks can be called as most economical and hence it can be referred for any type of construction work.
