atterberg limits relationships 1Liquid index, abbreviated as LI, also called liquidity index, a dimensionless number, is scaling the natural moisture content of a soil sample to the liquid limit and plastic limit.

 

Liquid Index formula
\(\large{ LI =  \frac{ PL \;-\; w_n }{ LL \;-\; PI }   }\) 
Symbol English Metric
\(\large{ LI } \) = liquid index \(\large{dimensionless}\)
\(\large{ LL } \) = liquid limit \(\large{dimensionless}\)
\(\large{ w_n }\) = natural water content (moisture content) \(\large{dimensionless}\)
\(\large{ PI }\) = plastic index \(\large{dimensionless}\)
