REVIEW PAPER ON EFFECT OF COIR FIBRE REINFORCEMENT ON THE STRENGTH PARAMETERS AND CBR VALUE OF BLACK COTTON SOIL

Civil Engineering

In India, expansive soil makes up about 20% of the total land area. Because to the presence of clay minerals called "Montmorillonite," these soils are known to have poor qualities. Soil behaviour that is typical causes settlements, fissures, and other types of structural failure. Therefore, it is crucial to either remove the current weak soil and replace it with non-expanding soil or stabilise the weak soil to improve its qualities. One method for enhancing the engineering properties of expansive soils is soil reinforcement. It is not a new concept to use natural fibres to strengthen soil. In geotechnical engineering, randomly dispersed fibre reinforced soil has recently garnered more interest, The current dissertation attempts to investigate how various environmental factors affect the performance of coir fibres added to black cotton soil in order to increase its strength and lessen its tendency to swell. As a biodegradable substance, coir fibre is known to break down in harsh environmental circumstances, such as contaminated and polluted water, contact with leachate, alternating cycles of wetting and drying, alternating cycles of freezing and thawing, and so forth. Coir fibre in soil is typically expected to last eight to ten years. It may therefore deteriorate quickly in certain climatic conditions. It's possible to lose the increased soil strength or decreased edoema. This aspect has not yet been researched. This is why this is attempted in this study
