STABLIZATION OF CLAYEY SOIL USING SURKHI AND PLASTIC BOTTLES

Abstract

A significant part of entire country is surrounded by clayey soil. Clay soil is not suitable for settlement point of view because it goes for long term settlement. Clay soil has lower shear strength because of low value of angel of internal friction. Hence, clayey soils need to be stabilized to increase it’s strength, durability. Numerous researches have been completed on clayey soils to upgrade it’s properties. Soil stabilization is the most accurate method to enhance the geotechnical properties of soil. It is chiefly using for constructing the structures. This project focuses to conduct an investigation to examine the developments in properties of clayey soil analyzing physical properties of soil stabilized with surkhi and raw plastic bottles such as Compaction Curve (OMC and MDD), Unconfined Compression Strength (UCS) test, Liquid Limit Test and Plastic Limit Test. The tests were conducted in three phases. In first phase, the physical properties of pure soil were determined. In the second phase, various tests were performed on the soil with varying percentage of surkhi. The varying percentages of surkhi are as 5%, 10%, 15%, and 20% to 45%. In the third phase, various tests were performed on the soil with varying percentage of raw plastic bottles. The varying percentage of plastic bottles is as 5%, 10%, 15%, 20% to 25%.
