EFFECT OF GRANITE DUST ON INDEX PROPERTIES OF LIME STABILIZED BLACK COTTON

granite dust was prepared and the liquid limit, plastic limit and differential free swell were conducted as per relevant IS code of practise. The test results showed significance decrease in the expansive behavior of the Black Cotton Soil. The liquid limit and plasticity index decreases from 37 % to 28 % and 17.45 % to 4.80%, respectively if Black Cotton Soil is blended with 5 % lime and granite dust from 0 % to 30 % by weight of Black Cotton Soil. The test results reveal that the expansive behavior of the Black Cotton Soil is checked to a great extent
