UTILIZING NATURAL ADDITIVES IN STABILIZING CLAYEY SOIL

Some Clayey soil in Alkarak is stabilized using Cement and natural resources including zeolites and Dead Sea Sand (DSS) (south of Jordan). To examine how different additives can be used to improve the mechanical and physical qualities of problematic clayey soil, field and laboratory experiments have been done. Clayey soils are surface deposits that vary in thickness and mineral makeup. With varying percentages, the two main components are kaolinite and montmorillonite. Due to Jordan's semi-arid location and the soil's unsaturated state, Clayey soils are very vulnerable to changes in moisture content due to their sheet-like structure. As a result, infiltration depth varies depending on the area. The Ca-montmorillonite content and moisture content, which change between the summer and winter seasons, determine how troublesome Clayey soils respond, including swelling and shrinkage to varying degrees. Utilizing 4% (DSS), 12% (Zeolites), and up to 12% (Ordinary Portland Cement) improved the physical and mechanical qualities of the examined clayey soil. The Clayey soil could be improved by the 4% fixing percentage of (DSS). 12% of zeolites, meanwhile, improve the clayey soil's qualities. The physical characteristics of Clayey soil could be enhanced by mixing up to 12% ordinary Portland cement with it.
