Abstract

Shear strength is most important property of soil. It depends on particle interaction. Shear failure of soil occurs when particle slides over each other. When it comes to sandy soil then concern for shear strength increases, as the particles in sandy soil have only frictional force in between them. There is no cohesive force in between particles of sandy soil. The aim of this work is to investigate the variation in shear strength by adding coconut fiber. Coconut fibers are of brown color and are also known as coir fibre obtained from the outer shell of coconut. It is a waste material which can be utilized as a reinforcing material for soil. In this experiment 20 mm long coconut fibre are used to reinforce sandy soil and shear strength is evaluated by direct shear test. The result shows that there is 29% increment in shear strength parameter of sandy soil by adding coconut fibre.
