We added different proportions of magnesium chloride to an expansive clay and ‎performed ‎swelling, geotechnical characterization, and mechanical strength tests. The results show ‎that the swelling ‎potential and swelling pressure of the expansive soil were significantly decreased ‎by the addition of ‎magnesium chloride (MgCl2). This treatment also improved the physical and ‎mechanical characteristics and ‎microstructure of the soil. The soil’s plastic limit, shrinkage limit, ‎cohesion, and internal friction angle all ‎increased linearly with the addition of the MgCl2 stabilizer. ‎However, we observed that the liquid limit of the ‎soil decreased as the level of magnesium chloride ‎was increased.‎ %A Bahloul, Ouassila %A Abbeche, Khelifa %A Bahloul, Azzedine %P 249-262 %R 10.37190/msc192617 %U https://doi.org/10.37190/msc192617
