WebFor the soil like sensitive clay, the natural moisture content may be greater than the liquid limit and value of LI will exceed 1 in the condition. The heavily over consolidated soil deposits have the natural moisture content, which may be less than the plastic limit. In that scenario, the liquidity index is smaller than 1. WebMay 24, 2024 · In very sensitive clay deposits, pore water salt content could be today lower than 1 g/L. The reduction of the liquid limit and of the plasticity as well as the reduction of the remolded shear strength associated with the reduction of the pore water salinity is today well documented. my ear hole hurts
