Experimental Study to Clay Stabilization Using Waste Pumice, Waste Marble Dust and Lime

In this study; pumice, marble dust and lime were mixed with high plasticity clay in order to investigate their effects on the engineering properties of clay. Atterberg’s limits, standard compaction, unconfined pressure test, swelling experiments were performed by adding pumice, marble dust and lime to clay in pre-defined ratios. After determining the optimum dosages for each additive, samples prepared at maximum dry density and optimum water contents were cured during 7, 28 and 90 days. Unconfined pressure tests, triaxial pressure tests and CBR tests were performed on those samples. SEM, X-Ray and chemical analysis were also performed. It was observed that the additives used improved the engineering properties of high plasticity clay.
