Abstract Expansive clays are considered problematic soils as they exhibit sizable massive volume changes with the change in moisture content. Such soils may cause damages to structures, utilities, pavement, etc. unless special measures are taken to reduce the risk of harm. Traditionally, swelling soils are entirely or partially replaced with nonswelling engineered fill. Alternatively, soil stabilization techniques are applied to reduce swelling potential using locally available materials. Mixing swelling clays with dolime fine is used as an improvement technique. Dolomite chips which are the end product of crushing dolomite stones, are used in various industrial applications, while dolime fine is produced from solid waste crushing. Dolime fine has a very high percentage of CaO. It has been recommended as a binding agent that can replace pure lime. So dolime fines can be utilized to stabilize expansive soil. Their strength and availability characterize dolomite chips. |
