Unsaturated soil mechanics has rapidly become an integral part of geotechnical engineering practice. The negative pore water pressure is the major interest in unsaturated soil situations. The present study was an attempt to examine the effect of saturation on strength and consolidation properties of two soils namely CH and CL type of soil at various percentage of maximum dry density (MDD). Result showed an apparent raise in the cohesion value of yellow soil increased with amplification in the saturation value as well as the density value. Black cotton soil followed a reverse trend of decrease in the cohesion as well as the angle of internal friction value with increase in degree of saturation, but comparatively increased for a given degree of saturation with increase in value of density. No definite trend was observed in the value of coefficient of consolidation. The work included few test on centrifuge to quantify the settlement of the selected soils at 80% saturation with 85% maximum dry density and 95% maximum dry density. The centrifuge showed an appreciable value of settlement for yellow soil with 85% maximum dry density at 80% saturation while the other tests showed some settlement but not to a measurable value.
