Amalgamation of E-waste plastics in concrete with super plasticizer for better strength

Abstract Concrete is a major construction material and plays a crucial role in the improvement of infrastructure development of any country and India is the second largest cement market both in production and consumption in the world in 2018. The idea of the conservation of coarse aggregate has been largely ignored despite the fact that coarse aggregates make up 40–50% of a concrete mix by volume. The quantity of cement and concrete production increase as the demand for developing the infrastructure increases day by day and the overexploitation of coarse and fine aggregates may reduce the resources to a crucial level, compromising the needs of future generation. Aggrandizement of technology has led to the boon and bane for the world. Earlier studies on E-waste showed that India has generated 0.4 million tons in 2010 which may increase to 0.5–0.6 million tons by 2013–2014, but the latest report confirms that India has produced 2 million tons of E-waste and it was one among the top ten countries which generates E-waste in abundance in the globe. The main objective of this study is to partially replace the E-waste plastics for coarse aggregate, to minimize the environmental degradation by E-waste and reusing the same in the required shape and to understand the behavior of M40 concrete in addition of super plasticizer by conducting various tests. The test result shows that properties of concrete in fresh and hardened stages have been improved. E-waste plastics can be used as coarse aggregates by replacing the coarse aggregates in a concrete by volume 0%, 12%, 17% and 22%. Utilization of plastic aggregate in concrete reduced overall unit weight of concrete and the strength of the concrete is gradually increased with the addition of different percentage of E-plastic waste.
