In a purely cohesive soil the critical center lies at the intersection of

If the soil sample is having porosity 50% and degree of saturation at 90% then its percentage air void is -

If the grain size of soil increases

The quantity of water retained by the sub-soil against gravity is known

On analysis of particle size distribution of a soil, it is found that D₁₀ = 0.2 mm, D₃₀ = 0.3 mm and D₆₀ = 0.8 mm. The coefficient of curvature, as given by the particle size of distribution curve will be -

Consistency index (IC) is defined as
where w is natural water content of soil, w_L is liquid limit of soil; w_P is plasticity limit of soil; IP is plasticity index of soil sample.

Cohesive soil are generally
