Rbi Grade 81

Chemical stabilization is one of the oldest methods of stabilization of problematic soil. In recent days, it has been investigated that addition of fibers will improve the ductility behavior of the soil there by reducing the development of crack during shrinkage. Extensive study has been carried out on the stabilization of expansive soils using various additives such as RBI, cement, flyash, industrial waste products etc., and also with random inclusion of fibers such as coir, sisal, polyester fibers etc. Randomly oriented tensile inclusions incorporated into soil to improve its load–deformation behaviour by interacting with the soil particles mechanically through surface friction and Effect of Random Inclusion of Coir Fibers on Strength Behaviour of RBI Treated Black Cotton Soil. This project describes the strength behavior of treated black cotton soil (BC soil) reinforced with local fiber. The various percentage of RBI Grade-81 as 2%, 4%, 6% and 8% was used to find out the optimum value of RBI Grade. local polymer has been randomly included into the RBI Grade treated soil at four different percentages of local fiber content, i.e. 0.5%, 1% 1.5%, and 2% (by weight of soil).

Reinforcing Material

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.
