Review of Liquefaction Potential of Sand with Plastic and Non Plastic Fines

Anjali Saji

Abstract: Soil in the field or on reclaimed land usually has less silt or clay than pure sand. The effect of fraction of plastic and non-plastic fines within sand matrix on liquefaction resistance was studied in many research works. In this review paper discuss about, clean sand was mixed with plastic and non-plastic fines having different plasticity indexes (PI) and the effect of liquefaction resistance was evaluated in terms of cyclic stress ratio and Laboratory-Based Correlation between Liquefaction Resistance with fines content. A series of undrained cyclic triaxial tests were carried out on loose, medium, and dense specimen. The results shows that liquefaction resistance tended to decrease as the plasticity index of fines in the specimen increased. Liquefaction resistance of loose sample had a small effect on the plasticity index of the fines.
