Experimental Study on the Additive Effects of Cyclic Freezing-Thawing on the Durability of Cement Soil

Abstract

With pumice as the additive agent used in cement composite soil . In order to test the mechanical performance of the composite cement soil, the unconfined compression resistance and freezing and thawing cycle test were done in the lab with different additive quantity(2%,4%,6%,8%,10%), different cement content(4%,8%,12%,16%,20%), different number of freezing and thawing(5,10,15,20,25), The results show that the strength of the composite cement soil are significantly increase with increasing cement content, before and after freezing-thawing the strength loss and mass loss are increase with increasing freezing-thawing number and cement content.
