WebLiquid Limits (WL) It is defined as the minimum water content at which soil has a tendency to flow. At the liquid limit, soil passes liquid state of consistency to a plastic state of consistency & visa-versa. At the liquid limit, all the solids pass same negligible shear strength of 2.7 Kn/m ², which can be just saturated. WebWe can notice if a soil is in plastic state then its liquidity index varies from 0 to 1. From these observations we can see liquidity index of soil begins from zero at plastic limit and with increase in the water content soil’s liquidity index increases and becomes 1 at liquid limit.
