A Expermental Study of Stabilization of Expansive Soil by using Fly Ash and Rice Husk Straw Ash

In India, Black cotton soil covers over one-fifth ofthe entire land area. These are mostly found in and aroundthe Deccan plateau.Black cotton soil is an expansive soil which proves problematic for the engineering work. Black cotton soil has low bearing capacity, high compressibility and swelling and shrinkage properties. To overcome on these engineering problems soil stabilization is the best solution. In our research we used the concept of chemical stabilization. We used fly ash and rice husk straw ash in different proportion with black cotton soil. The present paper briefly describes the experimental investigation carried out by adding fly ash and rice husk straw ash to black cotton soil for improving its engineering properties
