Behavior of Black Cotton Soil after Stabilization with Marble Powder

The black cotton soil is known as expansive soil due to its property of swelling and expansiveness with influence of variance moisture in soil. It also shows shrinkage behavior when dried. Due to these properties the strength characteristics are also affected adversely. The black cotton soil is also widely available in all around the world which leads us to wastage of land for construction uses to resolve this problem we can replace the expansive soil by non-expansive soil which is also a costly option so in this present paper we have stabilize a soil using waste material named marble powder which is a byproduct of marble industries. For the determination of properties we have performed atterbergs limit test, particle size distribution by wet sieve analysis, free swell index determination test, and linear shrinkage test on the sample of 50 % black cotton soil + 50 % marble powder. We have mark a great improvement in engineering properties of black cotton soil by stabilizing it with 50 % of replacement by marble powder. It also gives large decreament in swelling and shrinkage behavior of soil.
