Improvement in Shear Strength of Soil using Polypropylene and Coir Fiber

Abstract

The main objective of this study is to investigate the use of waste fibre materials in geotechnical applications and to evaluate the effects of waste polypropylene fibres and coconut coir on shear strength of saturated soil by carrying out soil samples. The results obtained and inferences are drawn towards the usability and effectiveness of fibre reinforcement as a replacement for deep foundation or raft foundation, as a cost effective approach. Our main aim in the project will be to find fibre content which improves shear strength of soil in most cost effective manner. We can thus conclude that addition of fibre improve the load bearing capacity of soil by increasing its shear strength.
