This paper presents the effect of RBI GRADE 81, LIME & CERAMIC DUST. The various properties of soil like liquid
limit, plastic limit, unconfined compressive strength, compaction characteristics, California bearing ratio and swelling pressure
of an expansive soil. Black cotton soil collected locally was blended with different percentage of stabilizer according to the
previous research which is conducted on individual stabilizer. From the analysis of test result, it was observed that plastic limit,
liquid limit, plasticity index, swelling pressure and optimum moisture content of soil decreases. Maximum dry density,
unconfined compressive strength and California bearing ratio increased with the percentage increase of stabilizer (lime, ceramic
dust, RBI grade 81). As an effective analysis It was founded that on comparison of above three stabilizer RBI grade 81 gives
better result between 3% to 6% addition to the soil can be used in enhancement of soil properties.
