Clay soils exhibit generally undesirable engineering properties. They tend to have low shear strength which reduces further upon wetting or other physical disturbances. Hence, there exists a need for improving the engineering properties of this soil before construction. Glass waste poses significant environmental challenges due to its non-biodegradable nature, resource-intensive production, and energy consumption during manufacturing. One solution to this crisis lies in recycling and reusing wastes into useful products. Coir fibre as a reinforcement material can be attributed to its unique combination of properties, including high tensile strength, flexibility, and biodegradability. The long and coarse fibres extracted from the coconut husk exhibit remarkable strength, making them an ideal candidate for reinforcing composites and materials. The main objective of this study is to investigate the effect of waste glass powder in geotechnical applications along with 2 cm coir fibre as a reinforcement which is randomly distributed and to evaluate its effects on shear strength and compressibility of clayey soil. The powdered glass material is added to the soil in different proportions of 0.5, 1, 1.5, and 2% of soil by keeping coir fibre constant as 0.5% and optimum proportion is evaluated.
