Q1:

The consistency index of a soil is defined as the ratio of

A liquid limit plus the natural water content to the plasticity index of the soil

B liquid limit minus the natural water content to the plasticity index of the soil

C natural water content of a soil minus plastic limit to the plasticity index of the soil

D natural water content of a soil plus its plastic limit to the plasticity index of the soil.

ANS:B - liquid limit minus the natural water content to the plasticity index of the soil

CI = (Wl-WN)/Ip.
