Enhancement of Shear Strength Parameters of Clayey Soil by using Polypropylene Fiber

Abstract

When the foundation soil is not strong enough to hold on with the loads transmitted to it .At such places the structure could be damaged, in order to eliminate this threat the soil properties such as stability, shear strength, durability etc are enhanced by mixing it with different admixtures such as lime, cement etc .At some occasions fibers (obtained from waste materials)are used to enhance the soil properties. In past a large number of studies have shown the effectiveness of such mixing materials at considerable percentages. It has been studied that the outcome of such materials when used in soil improvement techniques is handsome. In this examination the polypropylene fiber ,obtained from waste materials has been used. The different percentages of fiber reinforcement are used and the corresponding changes in the shear strength parameters are examined. The effects of polypropylene fiber reinforcement on the soil samples are examined by carrying out Direct Shear Test and Unconfined Compression Test.
