Stabilization of Expansive Clay with Mill Scale and Lime

This research paper reveals about study of Mill Scale (MS) for stabilization of soil sample. Mill Scale (MS) is extracted from iron/steel industries as waste product. This MS contains high amount of silica iron content and also lime, which acts as binding material. Basic properties of soil like Atterberg’s limits, compaction characteristics and strength characteristics were determined. The soil sample was treated with different percentages of lime and optimum percentage for soil is fixed (3%) and varying percentage of MS (5%, 10%, 15% and 20%) was treated with soil sample . Maximum dry density of soil decreases with increase in MS and lime content and optimum moisture content increases. The strength characteristics of the soil sample increasing up to 10% MS with 3% lime for soil sample and decreases after that. This justifies that usage of Mill Scale at 10% and 3% usage of lime gives high strength for soil.
