The study on potential usage of industrial waste products and other wastes in the concrete is going on globally. In this study an attempt has been carried out to explore the utilization of plastic wastes in concrete. Four different types of Light Weight Plastic Aggregates (LWPA) are prepared from the non-recyclable plastic bags of size 20-40μ thick by heating on a container at 120-150 oC. 100% replacement of Natural Aggregate (NA) with different types of LWPA is carried out, based on trail mix a suitable mix proportion was arrived. The compressive strength and Ultrasonic Pulse Velocity (UPV) tests for different types of plastic aggregate and conventional aggregate concrete are carried and outcomes are analyzed. The replacement of NA with LWPA reduces the density of the concrete and overcome the double issue of safe disposal and raw material shortage of non-recyclable plastic wastes.
