Industrial activities in India are associated with significant amounts of non-biodegradable solid waste, waste plastic being among the most prominent. This study involved 86 experiments and 254 tests to determine the efficiency of reusing waste plastic in the production of concrete. Thirty kilograms of waste plastic of fabriform shapes was used as a partial replacement for sand by 0%, 1%, 2%, 2.5%, 3% and 5% with 80 kg of concrete mixtures. All of the concrete mixtures were tested at room temperature. These tests include performing slump, compressive strength, cost analysis, and weight analysis. 14 cubes were molded for compressive strength and dry density tests, Curing ages of 3, 7, 14, and 28 days for the concrete mixtures were applied in this work. The results proved the arrest of the propagation of micro cracks by introducing waste plastic of fabriform shapes to concrete mixtures. This study insures that reusing waste plastic as a sand-substitution aggregate in concrete gives a good approach to reduce the cost of materials and solve some of the solid waste problems posed by plastics.
