Strength behaviour of kerosene coated coir fiber-reinforced expansive soil
Coir fibers are extracted from the husks surrounding the coconut. Coir fibers can be effectively used as reinforcing material but it has less durability and hence coir fiber coated with kerosene is used as reinforcement in the present study. The objective of the present investigation is to study the strength behavior of expansive soil reinforced with 5mm long randomly distributed kerosene coated coir fibers in 0% (unreinforced), 0.5%, 1% and 1.5% by dry weight of soil. Water absorption (WA) tests were conducted on uncoated and kerosene coated coir fibers. The WA tests were also conducted on kerosene coated coir fibers mellowed for a period of 1 day, 2day and 3 day. Water Absorption Capacity (WAC) of kerosene coated coir fiber reduced as compared to that of uncoated coir. It is found that 1% of coated coir fiber is the Optimum Coir Content (OCC) from view point of Unconfined Compressive (UCC) strength. Splitting tensile strength of OCC reinforced soil is increased by 50% that of unreinforced soil.
