CHARACTERIZATION OF CEMENT KILN DUST STABILIZED BLACK COTTON SOIL

Prathap Kumar, Sapna Devendra

Abstract: Cement kiln dust (CKD), being a waste product from cement industry is explored in the present study as a stabilizing material for black cotton soil(BC soil). In the present study, characterization of BC soil for Atterberg’s limits, Specific gravity, pH, compaction characteristics and unconfined compressive strength were conducted by admixing with CKD at different percentage. The results of the present study indicates that, both liquid limit and plastic limit increases with increase in CKD percentage. It was found that UCS increases with increase in curing period for BC soil admixed with 12%CKD. It was concluded that 12% CKD produce optimum benefits in terms of reduction in plasticity and increase in strength of BC soil admixed with CKD. CKD being an industrial waste thus can be used to stabilize BC soils to improve its engineering performance as a stabilized material.
