Utilization of E-waste as a Partial Replacement of Coarse Aggregate in Concrete

Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling or disposal are also considered as e-waste. Informal processing of electronic waste in developing countries may cause serious health and pollution problems, as these countries have limited regulatory oversight of e-waste processing. Solid waste management is one of the major environmental concerns in our country now a day. The present study covers the use or recycled e-wastes as replacement of coarse aggregates in concrete. The main aim of the study is to investigate the change in properties of concrete with the addition of e-wastes in concrete. It is found that the use of e-waste aggregates results in the formation of lightweight concrete. In this dissertation coarse aggregate is partially replaced by coarse aggregate upto 25% with regular interval of 5%,along with fly ash partially replacing cement in concrete of grade M40 and properties like workability, compressive strength and flexural strength is evaluated.
