REVIEW ON EFFECTS OF FINES CONTENTS ON ENGINEERING PROPERTIES OF SANDFINES MIXTURES

Sand with significant amount of fine is always encountered in the geotechnical project therefore the objective of this review paper is to study the behaviour of sand silt mixture with varying percentage of fine and to observed the volume change behaviour of sand with the varying percentage of fine. The test procedures were performed on specimens of different cases: a) constant void ratio index b) based on different relative densities c) different confining pressure such as 50kpa, kpa, 100Kpa, 150Kpa. The test results obtained for both the constant-void-ratio-index and constantrelative-density by the various researcher showed that as fines content increased, the internal friction angle decreased, from the previous literature review it is observed that the fine percentage ulterered the mechanical behaviour of sand. Again it is observed that the strength and liquefaction potential of soil increases as the percentage of fine increases to the certain extent.
