A STUDY ON THE RELATION BETWEEN CONSOLIDATION COEFFICIENT AND PLASTICITY INDEX OF FINE-GRADED SOILS

Abstract

Consolidation coefficient (Cv) is one of the key parameters in calculation of soil settlement rate. This parameter can be determined using one-Dimensional consolidation test. Prediction of Cv in fine- graded soils with different Liquid Limit (LL) and Plasticity Index (PI) is also substantial to have a better understanding of soil behavior. In the present study, two fine-graded soils encompassing a broad range of liquid (LL) and plastic limits (PL) are selected and conventional consolidation tests are conducted on these samples. The samples are tested using their natural water content. It was observed that increasing liquid limit and plasticity index decreases Cv.
