Utilization of waste materials and byproducts is a partial solution to environmental and ecological
problems. Use of these materials not only helps in getting them utilized in cement, concrete and other construction materials, it helps in reducing the cost of cement and concrete manufacturing, but also
has numerous indirect benefits such as reduction in landfill cost, saving in energy, and protecting the
environment from possible pollution effects. Electronic waste, abbreviated as ewaste, consists of discarded old computers, TVs, refrigerators, radios – basically any electrical or electronic appliance
that has reached its endoflife. Efforts have been made in the concrete industry to use non biodegradable components of E waste as a partial replacement of the coarse or fine aggregates. An experimental study is made on the utilization of Ewaste particles as coarse aggregates in concrete
with a percentage replacement ranging from 0 % to 30% on the strength criteria of M20 Concrete. Compressive strength, Tensile strength and Flexural strength of Concrete with and without Ewaste as
aggregates was observed which exhibits a good strength gain. Ultrasonic tests on strength properties
were executed and the feasibility of utilizing E plastic particles as partial replacement of coarse
aggregate has been presented
