 Abstract

The increasing tempo of construction activity has led to the requirement of good soil whose availability is less hence, there is need of improving the soil condition which can be accomplished through ground improvement methods. Among all the ground improvement techniques, soil reinforcement is emerging as an attractive alternative. The addition of natural fibre to the soil is very good soil reinforcement technique. Coir fibre extracted from the outer shell of the coconut can be effectively used to tackle many short term stability issue in geotechnical engineering. Coir fibre having high lignin content and less cellulose content than fibres such as flax and cotton, which makes it stronger but less flexible. Coir is bio-degradable product and it takes approximately 20 years to degrade over the ground and with suitable coating takes about 4-5 years to decompose under the burial condition. It is moth-proof, resistant to fungi and rot, provide excellent insulation against temperature and sound, not easily combustible, flame-retardant, unaffected by moisture and dampness, tough and durable, resilient, spring back to shape even after constant use and have low thermal conductivity and bulk density. The present study is focussed on modifying the geotechnical properties of soil by reinforcing it with different percentages of coir fibre in the soil obtained from the Gautam Budh Nagar region of District, Delhi NCR. For this study coir fibre was purchased from the local market of New Delhi. The study is conducted in two phases. In the first phase, the geotechnical properties of soil were studied by conducting laboratory tests. In the second phase, soil mixed with four different percentages of coir fibre i.e., 0.25 %, 0.50%, 0.75%, and 1% were subjected to various tests.
