In India, the expansive soil is one of the major soil deposits. They exhibit high swelling and shrinking when exposed to changes in moisture content and hence have been found to be most troublesome from engineering considerations. It is also known as “Black cotton soil”. Because of its high swelling and shrinkage characteristics, the Black Cotton soil has been a challenge to geotechnical and highway engineers. Geotechnical engineer recommend a verity of preventative techniques for soil to control of expansive soil. Recently many researchers used industrial waste in soil stabilization as low cost materials and to save the environment. Foundry sand is basically fine aggregate. This includes many civil engineering applications such as embankments and Portland cement concrete. Foundry sands have also been used in agriculture as topsoil. The largest volume of foundry sand is used in geotechnical applications such as embankments, site development fills and road bases. This paper brings out the results of experimental program carried out in the laboratory to evaluate the effect of mixing different proportions of foundry sand with clayey soil on compaction and California bearing ratio. Results show that addition of foundry sand reduces the swelling, plasticity index and increases the CBR value of soil.
