Abstract: The rising value of construction materials in many countries needs to research and implement of different alternative materials in civil engineering construction .In India, concerning 890 million tonnes of solid wastes are being generated annually as byproducts throughout industrial and agricultural. The Above wastes can be used as aggregate in concrete for the production of light weight concrete. Amid this study, coconut shell is utilized as light-weight mix in concrete. The undertaking paper goes for examining split tensile strength and compressive strength characteristics with complete replacement of coarse combination with coconut shell to supply light-weight concrete and to exchange cement by exploitation silica fume as admixtures with completely different percentages (0%, 10%, 15%, 20%, 25% and 30%) to urge smart strength like standard concrete. Concrete 63 cubes and 63 cylinders are casted with mix proportion (1:1.47:0.65) and their mechanical properties are determined and compared with standard concrete. The employment of coconut shells as for standard aggregates ought to be inspired as an environmental protection and construction value reduction measure.
