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 Atterbergs 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.

There are many techniques for soil stabilization, including compaction, dewatering and by adding minerals to the soil.

General information[edit] The prime goal of soil adjustment is to enhance the California Bearing Ratio of in-situ soils by 4 to 6 times
