Experimental Study on the Effects of Pumice Powder to Cement Soil

Abstract:

With pumice as the additive agent used in cement composite soil . In order to test the strength of the composite cement soil, the unconfined compression resistance were tested in the lab with different additive quantity (4%,8%,12%,16%), different curing periods (7d,28d,60d), The results show that the strength of the composite cement soil are significantly increase with increasing curing periods , with increasing additive quantity the strength variation of the composite cement soil first added, and then reduces. there is an optimum amount 8%.The pumice powder may evidently improve the mechanical properties of soft soil which has the characteristic of rich-water content, when water content from 12% to 19%, the strength of the composite cement soil are increased about 20%.
