Performance of Concrete with Waste Plastics and M-Sand as Replacement for Fine Aggregate

In recent days, there is an intense need for an alternate cost effective and sustainable raw material for concrete which does not make the structure inferior in strength. An experimental study on the utilization of the waste plastic and M-sand in the place of river sand and aggregate partially was performed in paper. In the scenario of scarcity of river sand due to the territorial government action and restriction of usage because of the eco and environmental consideration, M-Sand is found to be an effective replacement and cost effective material. Concrete specimens were casted with combination of M-sand and plastic waste with 5%, 10%, 15%, 20% and 25% and compared against control mix. Cube test for compressive strength study, cylinder test for split tensile strength study and prism test for flexural strength study were done with the proposed concert mixture. All the specimens and tests were done for different curing period of 7, 14 and 28 days. The results obtained from the proposed mix of concrete are compared with the conventional concrete mix specimen respectively. The replacement of fine aggregates reduces the quantity of river sand to be used in concrete and also plastic fibres are proved to be more economical. Positive performance of the concrete with waste plastic and M-Sand as partial replacement of river sand was observed on all the experiments and found optimal in sustainable and economical performance.
