Expansive soils, steel slag, binders, CBR and UCS.

Abstract

Expansive soils are containing the swelling minerals such as illite and montmorillonite, they may cause extreme damage to structures, especially when these soils are subjected to wetting and drying conditions. High expansion and reduction in shear strength and subgrade strength will take place due to the increase in water content of these soils. The by-product of steel slag increasing day to day with a huge quantities and it is a major problem to disposal it. In this work, the by-product of steel slag and binders(cement) are varying percentages of, 0, 5, 15, 20 & 30% and 0, 2%, 4%, 6% are added to the expansive soil to improve the strength of the subgrade of pavements by conducting the California Bearing Ratio and UCS It was observed that the maximum strength attained at 20% of steel slag and 6% of cement of additives added to the expansive soils, beyond that there is a marginal variation.
