Impact of Calcium Chloride on the Microstructure of a Collapsible ‎Soil

Abstract

The study of the collapse of soils under the effect of flooding is a major problem in soil ‎mechanics. Most of the work done on the treatment of these soils has been devoted to ‎the use of binders of hydraulic or organic types. However, little work has been devoted to the use of salt calcium chloride in ‎collapsible soil treatments.‎ The purpose of this study is to evaluate the effect salt calcium chloride on a reconstituted collapsible soil in the laboratory, at ‎different levels of water content, compaction energy and concentration of the saline solution. The ‎results obtained showed a significant reduction in the potential for soil deformation ‎and an illustration and a noticeable interaction between the soil particles ‎and the saline solution resulting in a denser material.
