Expansive soil covers nearly 20% of the land mass in India. It shows major volume change due to change in moisture content. When the soil is dry it shrinks' and with increase moisture content swells. This is the major problem for geotechnical engineers. The stabilization is more advantageous method to treat the soft soil. It reduces the cost of the project using industrial waste materials. Utilization of industrial waste materials in the improvement of problematic soils is a cost efficient and environmental friendly method. It helps in reducing disposal problems caused by variousindustrial wastes. However, it is essential to understand the performance of these waste products prior to use. The present paper evaluates the potential of steel slag with fly ash to stabilize a soft soil. Soil sample were collected from Poondi, Coimbatore district. This soil was classified as per Indian Standard Classification System (ISCS). Dif erent amount of steel slag, i.e. 4, 8 and 12% with dif erent amount of fly ash, i.e. 3, 6 and 9% were used to stabilize the soft soil. The performance of steel slag with fly ash modified soil was evaluated using compaction compression permeability and index properties test.
