Abstract

In this paper, coconut coir an eco-friendly and cost effective material is used to reinforce the black cotton soil for rain water harvesting system which is used for agricultural purpose. In the present study the basic geotechnical and physico-chemical properties of the black cotton soil sample collected from Anantapur, Andhra Pradesh is analyzed. Coir is used as a reinforcement to increase the strength of the soil. A series of Compaction and UCC tests were conducted to study the effects of randomly distributed coconut coir fibre in the range of (0.5-2.5%) on black cotton soil. Tensile strength of treated and untreated coir fibers are found after reinforcing in soil for one week. Coconut coir fibers were also treated to improve the binding property of black cotton soil with sodium hydroxide, bitumen and kerosene to study the durability and strength. Coated and uncoated coconut coir reinforced in soil is tested till one month with interval times. Treated Coir fibers are placed in different positions in sample and strength of the sample is found till one month.
