Utilization of manufactured sand as fine aggregates in electronic plastic waste concrete of M30 mix

Abstract

Electronic waste generation is creating a major problem regarding the environment and human health. As per the Waste Electrical and Electronic Equipment Directive of the European Union, E-waste is the waste material comprising of any wrecked or undesirable electronic apparatus which incorporates PCs, amusement gadgets, cell phones, and other electronic things that have been disposed of by their unique clients. It is estimated that 51 million tonnes of E-plastic waste have been generated globally in 2019 in which only 9.1% is reused. At present, the cost and demand for coarse aggregates are also increasing day by day. Usage of E-plastic waste as a halfway substitution for coarse totals won't just clear route for eco-accommodating or green concrete yet also decreases the gigantic heap of these wastes on the soil by which indigenous habitat is protected. This study focused on replacing natural coarse aggregates with E-plastic waste in the range of 0–16.5% and full replacement of fine aggregates with M-sand for M30 mix. The obtained results show that the 28 days compressive strength increased by up to 3% after 5.5% replacement of E-waste and then decreases for 11% and 6.5% replacement of E-waste. The Flexural strength results and Split tensile strength results show increment for 5.5% and 11% replacement and decrease for 16.5% replacement. Therefore, up to 11% replacement of coarse aggregates with E-plastic waste gives better results when compared with conventional concrete.
