Stabilization of Black Cotton Soil by Using Rice Husk and Bagasse Ash

Abstract

Abstract: Black cotton soil is expansive type of soil that expands suddenly and starts swelling once it comes in contact with water. The strength of the soil is very poor due to its physical properties. Expansive soils exhibit improved response in behaviour with different types of stabilizers. Stabilization with admixtures is found to be an effective technique to improve the strength properties of the black cotton soil. During this study the potential of rice husk ash and bagasse ash are found to be useful admixtures to improve the strength properties of the expansive soil. The rice husk is an agricultural by-product from rice milling and bagasse ash is a sugarcane waste from sugar industry. In this research an approach is made to improve the properties of black cotton soil with combination of bagasse ash and rice husk ash. The results show substantial improvement in engineering properties of black cotton soil with the admixtures. Keywords: Black Cotton Soil, Rice Husk Ash, Bagasse Ash.
