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.

Modification of the Geotechnical Properties of Loess Using Eggshell Waste (El'Mghair Region)

“…Algeria's diverse geological and climatic conditions have long necessitated innovative solutions to address the distinct challenges associated with loess soils. In this context, various soil stabilization techniques have been explored, including stabilization with lime [7,8], cement [9][10][11][12], slag [13,14], chemical additives [15][16][17][18], as well as geosynthetics [19][20][21]. These methods have been employed to varying degrees of success, but the utilization of waste materials like eggshell waste represents a sustainable and potentially cost-effective alternative.…”

The Estimation of One-Dimensional Collapse for Highly Gypseous Soils

“…Gypseous soils are considered metastable or collapsible soils, and a large number of researchers have estimated the collapse potential for high Gypseous soil using the double oedometer test which was proposed by Jennings & Knight (1957) [4][5][6][7][8][9][10]. The collapse potential value is correlated with a qualitative collapse classification as shown in Table 1.…”
