For assessing the suitability of foundation soil for engineering purpose and to initiate appropriate measures to make it fit for construction, studies on the soil-pollutant interactions are essential. Previous studies have reported that salt solutions can cause significant changes in the geotechnical properties of soil. Salts may occur in the soils through precipitation, irrigation, fertilization, leachate from landfills etc. Salinity causes costly damage to urban infrastructure every year. Thus in this study the effect of certain salt solutions on geotechnical properties of soil like liquid limit, plastic limit and free swell are determined. The salt solutions used are Sodium Chloride, Magnesium Chloride and Calcium Chloride. Two types of clayey soil belonging to CL and CH classifications were used for the study. The experimental results indicated considerable changes in the properties of soil.
