STABILISATION OF SILTY CLAY SOIL USING CHLORIDE COMPOUNDS

The object of this paper is to investigate the effect of adding different chloridecompounds including (NaCl, MgCl2, CaCl2) on the engineering properties of siltyclay soil. Various amounts of salts (2%, 4%, and 8%) were added to the soil tostudy the effect of salts on the compaction characteristics, consistency limits andcompressive strength. The main findings of this study were that the increase in thepercentage of each of the chloride compounds increased the maximum dry densityand decrease the optimum moisture content. The liquid limit, plastic limit andplasticity index decreased with the increase in salt content. The unconfined compressive strength increased as the salt content increased.
