A Comparative Study on Cement Kiln dust Stabilized Expansive Soil with Plastic Waste and Sodium Chloride

A large number of infrastructure projects are being installed in almost every part of our country .The wastes of industries and agriculture adversely affect the environment as high land area will be required for their disposal and when they disintegrate, results in the production of harmful gases causing, soil contamination, land fill space and many other hazardous effects. In India, the rate of generation of solid waste is found to be increasing at a very rapid rate in past few years. Soil stabilization is a process that improves the engineering properties of soil such as strength, volume stability and durability. Expansive soils are those whose volume changes significantly when it comes in contact with water and are therefore, problematic to structures. Extensive laboratory trials have been carried out by various researchers and had shown promising results for application of such expansive soil after stabilization with additives such as sand, silt, lime, fly ash, etc. The present study was planned to compare and evaluate the influence of Plastic waste and Sodium chloride in varying percentage to further improve the expansive soil replaced with optimum Cement Kiln Dust percentage. Laboratory tests will be carried out and results are analyzed & reported.
