- Expansive soils are widely distributed approximately one-sixth of the total area of our country. Expansive soil causes great damage to infrastructures is very common. In view, construction of buildings on unsuitable ground is not able to be avoided and making a suitable ground before constructions is real challenging issue for Geotechnical Engineers. To overcome the difficulties experienced by the expansive soil in geotechnical applications on one side and safe disposal of solid wastes on the other side, an attempt is made to investigate the possibilities of utilizing the solid wastes to improve the strength and engineering behaviors of the expansive soil. In this, present investigation the type of solid waste namely Rice Husk Ash for stabilization is selected to study the effects and engineering characteristics of the expansive soil. The present study deals with the strength behavior of the expansive soil collected from Rellugadda nearby Amalapuram, East Godavari district, Andhra Pradesh, India.The rice husk ash is mixed with soil in various
proportions like 5%, 10%, 15%, 20%. The various tests are conducted on these proportions of rice husk ash and tests have been carried out and results were reported in this paper.
