A REVIEW PAPER ON STABILIZATION OF EXPANSIVE SOIL USING FLY ASH

Abstract

Construction is one of the important parts of Indian budget and is an essential part of the development. Today About 51.8 million hectares of land in India has swell-shrink soil(Black Cotton soil).Characteristics of swell-shrink soil,is that they are very hard in dry state but they lost their strength when get wet .this soil create problem to construction, it is major challenge for geotechnical engineering to overcome this problem. Soil stabilization is widely used in foundation and road pavement construction. This is done by improving the soil properties like volume stability, strength, durability. In this process removal or substitution the problematic soil is done. To get better result we are using additional materials such fly ash obtained from thermal power plant. With various proportions of this ash i.e. 10%, 20% & 30% the problematic soil is stabilized..
