Effect on Strength Characteristics of Expansive Soil Using Sisal Fibre and Waste Materials

Amrutha Mathew | Dr. Raneesh. K.Y

Abstract: The addition of sisal fibre, bagasse ash and glass powder waste in various proportions with black cotton soil and combination on the above proportion of ingredients is studied. To achieve this goal experimental studies were carried in two phase. In the first phase, the physical properties of soil such as particle size distribution, specific gravity, Atterbergs limits, swelling pressure were determined. In second phase, various tests were performed on black cotton soil using different proportion of sisal fibre, bagasse ash, glass powder waste and from the maximum values of strength test a combination of 0.9 % sisal fibre, 7 % bagasse ash and 14 % glass powder waste was also performed. The results indicated that with addition of sisal fibre, bagasse ash and glass powder waste the dry density increased and optimum moisture content was found to be decreasing. The unconfined compressive strength and California bearing ratio values increased with addition of optimum percentage of sisal fibre, bagasse ash and glass powder waste to the mixture of black cotton soil. The best result was obtained for mixture of black cotton soil and optimum dosage of 0.9 % of sisal fibre, 7 % bagasse ash and 14 % glass powder waste.
