Abstract
Black cotton soil is an expansive soil. It is a boon for the farmhands but also a nuisance for civil engineers as it shows swelling-shrinkage behavior with seasonal variations in moisture content. Montmorillonite mineral kept the onus for this behavior. On field various additive i.e. fly-ash, lime, various bio-enzymes are being used for improving the swell-shrink behavior of black cotton soil. In the present paper, we will be analyzing the efficacy of waste marble dust to improve the swell-shrink behavior of black cotton soil. Following the research work, we found an effective dose of 30% marble dust by weight of black cotton soil. Results show an increase of 193% in CBR and around 43% in UCS value.
