Experimental Study on Freezing Point of GCL Bentonite

Abstract:

Structure of the impervious material GCL bentonite was destroied by the action of repeated freezing and thawing in irrigated areas in northren part of China, and the anti-seepage performance of the GCL was weakened. Freezing point is an index to identify whether the soil mass was in frosting state, it is very important for us to research infiltration law. This paper researches the relationships among the freezing point, density and water content. Using these relatively easily provide reference for the application of GCL bentonite in the future in the alpine region. The results show that the freezing point of GCL bentonite increases when the water content and density of GCL bentonite is increasing, and the freezing point of GCL bentonite with lower water content changes more distinctly with the density.
