STRENGTHENING AND EVALUATING OF BLACK COTTON SOIL BY USING RBI GRADE 81 AND LIME

CIVIL ENGINEERING

It is the era of reformation, low bearing capacity and high settlement behaviour of black cotton soil is the challenge for the engineers to work on it. To overcome this problem various techniques are used to increase the strength and durability of black cotton soil. Stabilization is the best technique which reduces the consistency limits of the soil. In this present study, experimental investigation are conducted to find out the improvement in the various engineering properties of soil after the addition of Lime and RBI grade 81 into the Black cotton soil. From the LL, PL, and PI tests on optimum mixes arrived, it has been found that the Liquid limit as well as plastic index decreases and Plastic limit increases by increasing the proportions of RBI grade 81, and Lime. The CBR and Standard Compaction tests were conducted on the optimum mix for Comparatively with normal black cotton soil, optimum mix.
