Cement concrete, popular building material, because of its mouldability in the plastic state and when solidifies becomes a hard material capable to take very high compressive strengths. About 70% of the concrete volume comprises of aggregates, which not only gives bulk to the concrete mix but also takes considerable amount of load. Properties of aggregates play a major role in defining the properties of concrete produced from it. This paper reports an experimental work carried out to study the effectiveness of e-waste to be used as partial replacement of Coarse aggregates. E-waste is the discarded electrical or electronic devices. M30 mix has been designed and the replacement levels tested were 10, 15 and 20%. For every replacement level slump test and compressive strength test is carried and reported in this paper. Use of electronic waste in concrete is one of the effective ways of disposing E-waste, which otherwise would be lying in landfills creating the environmental issues.
