“…Plastic limit initially remains almost constant up to a KCl content of 3%, but later, it increased with the increases in quantity of KCl up to 9% of soil weight. Plastic limit does not change significantly with addition of KCl, which is quite different from the results of Al-Omari [8], where a significant increase in the plastic limit of expansive soil was observed. This may have been attributed to the lower plasticity of soil used in the study as compared to latter one.…”

“…However, for higher quantity of KCl, it reduces with a low rate. Figure 3 also shows that the rate of decrease in PI is relatively higher in case of Al-Omari et al [8] than the present study. It may have been attributed to the difference in plasticity of soil used in both the studies.…”

“…The reduction in liquid limit indicates the reduction in soil compressibility. Though, the LL decreases in both cases (present study as well Al-Omari et al [8]), the efficiency of KCl seems to be higher in case of Al-Omari [8].…”

“…The results of present study are compared with the results of Al-Omari et al [8]. The influence of KCl on various properties of expansive soil is discussed separately on sections namely; Atterberg limits, compaction parameters, strength of soil and expansivity of soil.…”

“…Frydman et al [6] used KCl (0-9% by weight) to stabilize expansive soil, and found that the activity of soil has reduced significantly. Al-Omari et al [8] mixed more than 99% pure potassium chloride in expansive soil. It was found that KCl reduced the optimum moisture content, liquid limit and plasticity index of the soil.…”

Expansive soils cover more than twenty-two percent of geographical area of India. These soils shrink and swell, respectively, with the decrease and the increase in water content of soil. In this study, experimental tests were conducted on an expansive soil to study the effect of mixing of potassium chloride on various soil properties. Liquid limit, swelling potential and plasticity index were found to be reduced significantly with mixing of potassium chloride. Initially, for potassium chloride of 6-8%, plastic limit has also been reduced but latter, it increased with the increase in quantity of potassium chloride. Mixing of potassium chloride increases and decreases, the maximum dry density and optimum moisture content, respectively. The mixing of potassium chloride increases the unconfined compressive strength and shrinkage limit of soil. Optimum amount of potassium chloride is found to be approximately 8-9% of dry soil weight. Potassium chloride altered the properties of expansive soil significantly, and most of the modifications are found to be favourable from civil engineers' point of view. Results of the present study are compared with previous study results too.
