Abstract

Expansive soil possesses peculiar properties such as swelling and shrinkage. In monsoon, these soils absorb water and swell, whereas in summer they shrink due to evaporation of water. Due to such behavior of soil it is inappropriate to rely on the strength characteristics of these soils. In order to improve the soil characteristics, different stabilizing materials are used in varying percentages, so that they can match the specifications of the construction industry. Generally, various waste byproducts of certain industries are required to be used as stabilizers in order to achieve the goal of their disposal as well as its utilization to improve the properties of the soil. One such waste, called as the Foundry Waste was used to study the effect of such stabilization on the black cotton soil which is an expansive soil. This study is an attempt to analyze the effect of Foundry waste on Expansive soils, for improvement in compressive strength and swelling-shrinkage characteristics and increase its suitability for effective use in construction. The swelling and shrinkage of a soil layer of expansive soil results into failure in the form of settlement and cracking. Use of foundry waste to stabilize soil is an attempt to establish how the waste material with no significant application, can be used in construction industry and replace their chemically manufactured counterparts. The proportion for addition of foundry dust was taken as 10%, 20%, 30%, 40% and 50% for optimum utilization of waste material and to understand the behavior of Expansive Soil blended with it by performing various tests.
