The Effect of Mixing Method on the Permeability Changes of Cement—Bentonite

Abstract

In researches conducted on various materials to stabilize soils, different factors have been investigated but none of the researches conducted has focused on method of incorporation or mixing.Hence, in this study the effect of cement—bentonite incorporation method with both wet and dry methods in 14.7 and 28 curing time will be studied to show its effect on the permeability coefficient changes. The results obtained in this study showed that the effect of incorporation is visible in all samples, so that most of the samples, which were prepared dry, the slope of their e-Log k curve is less than the wet samples which shows the sensitivity of wet samples to dry samples due to permeability coefficient changes .The results of this study can be used in preparing the underground waste storage tanks.
