Effect of Waste Fly Ash and Rice Husk Ash on Residual Soils

In developing countries like India, due to remarkable development in road infrastructure, soil stabilization has become major issue in constructional activity, stabilization is not only a method of altering or modifying of one or more soil properties to improve the engineering. Characteristics and performance of a soil, but also processing available materials for the production of low –cost design and constructionBlack cotton soils which expand when moisture content of soils is increased the clay mineral Montomorillonite is main responsible for expansive characteristics of soil. the expansive soils called swelling of soils or black cotton soils a large part of south India is covered with expansive soil another problem with this soil is strength is decreases with increases of degree of saturation heavy damages may occur buildings roads runways pipe lines and other structures built on such soils if proper preventive measures are not method. The damages can be prevented to a large extent if characteristics of expansive soil properly assessed suitable measures taken in design construction and maintenance of structures built on soils. This presents experimental investigation to study the effect of Rice husk ash and Fly ash on swelling and shrinkage and mechanical properties of a soil. After finding out the experimental results in lab to know the evaluation and performance of RHA and FA ash on the black cotton soil in the laboratory. Black cotton soil and FA and RHA has prepared by varying of different proportions with respect to dry the density. Kotagiri Manoj Kumar | P.
