Stabilization Of Black Cotton Soil By Using Type-C Glass Fiber

One method for rehabilitation of weak and problematic soil properties is rehabilitation by using physical added material such as fibres. Black cotton soils, widely used in construction, often exhibit limitations in strength and stability, particularly under changing moisture conditions. Type C class fibres, known for their high tensile strength and durability, are introduced as a reinforcement material to enhance the soil’s performance. In this project, effect of glass fiber on rehabilitation of Black cotton soil mechanical properties are studied. The main goal of this project is evaluation of how added glass fiber to black cotton soil can affect engineering properties of soil, particularly unconfined shear strength of reinforced soil. In this project different composition of soil and glass fiber (0.5 to 2.5) percent with 12, 14 and 16 percent water content are used. In order to study the effect of water contain and glass fiber, unconfined compression tests have been done on Black cotton soil reinforced by fiber glass and unreinforced Black cotton soil. The results will reveals that the inclusion of glass fibers significantly improves the unconfined shear strength and mechanical properties particularly at higher water contents, where soil tends to weaken.
