The object of this paper is to investigate the effect of Common Salt (NaCl) on the index properties of Black Cotton Soil. Various amounts of Common Salt (0%, 2%, 4%, 6% and 8%) were added to the soil to study the effect of Common Salt on consistency limits or index properties. The Common Salt (NaCl) for the study is collected from shop in Damohnaka, Jabalpur (M.P) and the soil sample collected from behind Jabalpur Engineering College, near N.C.C campus, Jabalpur (M.P). Based on consistency Index and free swell the soil falls under highly expansive soil category. The extent of modification of properties depends not only on the nature of contaminant, but also on the type of soil such as physical nature, chemical composition and metallurgical properties. These contaminants may be inorganic, organic Solvents or organic matter. Test results showed significant improvements upon the use of Common Salt (NaCl). The plasticity index reduced from 22.6 to 16.84. The free swell value reduced from 41% to 19%. The liquid limit decreased from 45.05% to 34.89%. The plastic limit decreased from 22.6% to 18.41%, also increase in shrinkage limit from 13.48% to 15.76% is observed.
