abstract = "In the present study, expansive soil from outskirts of Bhubaneswar city (20°11′06.7′′N 85°47′23.7′′E) was characterized for its index properties. Grain size distribution revealed a 40 and 52% fraction of silt and clay, respectively. Soil was highly plastic with plasticity index of 22% and activity of 0.42. Maximum dry density (MDD) and optimum moisture content (OMC) of soil were appeared to be 16.4 kgN/m3 and 19.6%, respectively, with a very high degree of expansion. This soil can be considered problematic at present condition and therefore investigations are made to reduce its swelling potential and shrinkage ratio using dross (alumina refining waste) for the reduction of swelling potential of expansive soil. Highest reduction of swelling potential was appeared to be 92% with shrinkage ratio of 1.17, when equal amount of soil and dross were mixed. This study not only revealed the stabilization of expansive soil but also thrust on the management of industrial waste.",
