Soil contamination included oil, chemical, heavy metals and organic contaminant. High concentration of chemicals and toxic metals made the soil incapable for any intended engineering works. studies have been performed on contaminated soil and for their stabilization.In this work attempt has been made to study the effect of diesel oil on properties of local soil and then their stabilization with Fly Ash (FA) and Cement Kiln Dust (CKD). The stabilisation of contaminated soil by CKD improved the soil characteristics to some extent. The value of cohesion can be increased nearly linear ...
