UTILIZATION OF WASTE COIR FIBRE WITH POLYPROPYLENE FIBRE FOR SOIL STABILIZATION

Clay is an inorganic soil comprises of certain minerals that provide plastic properties while mixing with water. Because of the outperforming engineering properties of soil, it is used in construction sites such as road, building to strengthen the building/road foundation. In the dry state, clay soil behaves like a rock-solid, whereas coming in contact with water, behaves like plastic material. With the increase in the quantity of water, clay soil becomes sticky such as soften and cohesive. In this situation, clay stabilization is necessary and needed to enhance soil's engineering/mechanical properties. In this article, coir along with Polypropylene Fibre (PF) is used as a stabilizing agent to enhance the particle bonding. The fibres are added in percentage of 0.25 %, 0.50%, 0.75%, and 1%. The experiment shows that Maximum Dry Density, CBR and shear strength is obtained maximum at 0.75% of fibre content and hence considered as the best ratio to enhance the soil properties
