The objective of the present study was to understand the effect of calcium chloride on geotechnical properties of blackcotton soil. Black cotton soil collected from Siraguppa taluk, Bellary. It was subjected to various concentrations ofcalcium chloride viz. 0.1 N, 0.5 N, 1.0 N, 2.0 N and 4.0 N. Attempt was made to understand the effect of calciumchloride on index properties and engineering properties of black cotton soil. It was observed that the values of liquidlimit, plastic limit and plasticity index of the soil treated with calcium chloride was decreasing with increase inconcentration. Further the treated soil was investigated for compaction test. It was observed that the maximum drydensity of the soil was increasing at higher concentrations. However, no remarkable changes were observed in thevalues of optimum moisture content with increase in concentration of calcium chloride. The laboratory investigationwas made to obtain the unconfined compression strength (UCS) of treated soil. The soil was cured for 1 day, 7, 14and 28 days. It was observed that the values of UCS were increasing with increase in concentration at any curingperiod. The soil was further tested to obtain the effect of calcium chloride on permeability of treated soil. It wasobserved that the permeability is increasing with increase in concentrations of 0 N, 0.5 N, and 4.0 N.
