Abstract: Shear strength, compressibility, and permeability are three important properties of a soil mass. The geotechnical properties of a soil mass depend on the dominance of soil mineral in it. Forty different mixtures of Montmorillonite, Kaolinite, Illite, and Quartz were prepared to evaluate the liquid limit, plasticity index, clay sized fraction, activity, compression index, swelling index, and permeability. This study presents the variation of compressibility and permeability of soil with the proportion of minerals and relationship of compression index with liquid limit, activity and clay sized fraction. The research result shows that compression index exhibits a reasonably good relationship with liquid limit.
