Comparison on the Behaviour of Banana and S-Glass Fibre in Soil Stabilization

Abstract

Abstract: This (In natural state), The expansive soils are unsuitable for direct engineering applications because of their shrinkswell characteristics. Using stabilizing techniques, an effort has been made to enhance the soil's qualities. Fibres are one of the most often employedfor stabilizing soil in recent years due to their low cost and accessibility. Black cotton soil has been stabilized using treated banana and S- glass fibres as natural and synthetic fibres. The 4% NaOH solution is used to treat banana fibre, which results in a roughened surface that improves compatibility, tensile strength, bonding, etc. The soil is replaced with treated banana fibre from 0.5% to 2.5% at the interval of 0.5% and the same is repeated by replacing the soil with 1% to 3% of S-glass fibre at an interval of 0.5%. In this experimental investigation, there is marginal increase in dry density and strength at an optimum 1.5 % of treated banana fibre and strength for 2.5% optimum for strengthof S-glass fibre were obtained when mixed with soil. The soil stabilized with treated banana fibre showed better results when compared withthe s-glass fibre.
