Electrical and Electronic waste (e-waste) is increasing rapidly in the world, and is passing severe toxic waste issues to the human beings and the environment. About 80% to 85% of various electronic items, wastes are decomposed in landfills which might include or discharge lethal gases into air, may have an effect on human beings and environment. For solving and minimizing the discarding of huge quantity E-waste substance, recycle of E-waste materials in concrete production is well thought-out as the mainly possible purpose. It helps to eliminate the concrete materials deficiency issues that are currently going on in construction industry and it also helps to develop the strength of concrete mix and decrease the rate of concrete. In the current study, a novel attempt has been made by adding optimum weight polypropylene fiber with partial replacement of 20 mm E-waste particles as course aggregate. E-waste with pp fiber is employed in concrete in order to improve the strength of concrete mix. The work was carried out on M35 grade concrete specimen (without use of E-waste particles and pp fibers) and with a partial substitution of course aggregates with E-waste particles in range of 0%, 10%, 20% and 30% with respect to the weight of aggregate and pp fibers in the range of 0%, 0.2%, 0.4% and 0.6% with respect to the weight of cement. Comp. strength, Tensile strength and flexural strength of fibrous concrete with E-waste materials and not including e-waste materials as course aggregates was experimented which presented an excellent strength gain.
