Cement concrete is the most extensively used construction material in the world because of its great workability and can be moulded to any shape. In this modern age, civil engineering constructions have their own structural and durability requirements, depending upon its purpose and for this, modification in traditional cement concrete is must. Industrial waste is one of the major booming issues to dump in the Environment. The requirement of space for segregating the wastes is very difficult. On the view of recycling of waste, in this experimental study soft drink bottle caps are selected as partial replacement for the coarse aggregate in the concrete. Here an attempt is made to study the influence of cut bottle caps as partial replacement for coarse aggregates and studying the parameters like compressive strength, split-tensile and flexural strength of concrete. The size of caps as 3 mm width and 0.5 mm thick (approximately) is maintained in the concrete mix of Grade M20 with mix proportion 1:1.5:3, adopted with w/c ratio of 0.5. Bottle cap with 1%, 2%, 3% and 4% were added to the concrete as a partial replacement of coarse aggregate. Through this study, it can be seen that compressive, split-tensile and flexural strength of concrete has been increased as compared to conventional concrete by replacing coarse aggregates with bottle caps. Optimum strength were obtained at 2%.
