Reducing the greenhouse gas (CO2) emissions is the need of the world. Five to eight percent of total emission of CO2 of world is from the Cement industry itself. It is an established fact that the CO2 gas emissions are reduced by 80% in case of Geopolymer concrete vis-a-vis the conventional Ordinary Portland cement manufacturing. Also the State of Maharashtra tops in the list of all states of India which generates 20,270 tonnes of E-waste annually like Electronic waste and electrical equipment. Hence it is an emerging issue posing serious pollution problems to the human being and the environment. This project examines the possibility of reusing the nonmetallic portions of E-waste in concrete as coarse aggregates to increase its property compressive strength and also reduce greenhouse gas (CO2) replacing ordinary Portland cement by geopolymer. The project work is to make and to study the compressive strengths of Geopolymer concrete and Geopolymer concrete with E-waste as a partial replacement of the coarse aggregates ranging from 0 % to 30%, on the strength criteria of M20 & M25 grade concrete. The test specimens are prepared of size150x150x150 mm cubes & test shall be carried out after 7 days, 14 days and 28 days curing. This result is to be compared with conventional concrete on basis of strength, self-weight, economy & other structural parameters.
