Effect of Saline Water on Geotechnical Properties of Low Plastic Soil and High Plastic Soil

Abstract

In this research, the effect of water salinity on geotechnical properties of low plastic soil from Roukela and Bikaner clay was studied. In the Laboratory, several tests such as grain size distribution, specific gravity, Atterberg limits, standard proctor compaction test and modified proctor compaction test were done with distilled water and water of different concentration of NaCl. Results on Rourkela soil show that both liquid limit and plastic limit decreases with increase in salinity. Increase in salinity increases optimum moisture content and decreases maximum dry density. Results on Bikaner clay show that Liquid limit decreases with increase in salinity. There was not any significant effect on plastic limit of Bikaner clay when tested with salinity.
