Construction industry with its wide scope and specializations in various Civil Engineering branches became a possibility with the introduction of new construction techniques, equipment and building materials worldwide. The much anticipated and foreseen upset in development is picking up energy. Analysts and different foundations are taking innovation to the following level. Advancement in concrete and different other development materials has been forceful and serious. The overall market for development totals is extended to progress to 51.7 billion T in 2020, speaking to a yearly development pace of 5.2%. Natural resources for construction materials are depleting and disappearing at a very fast pace. Hence the need for alternative materials and methods are important. On the other hand, disposal of plastic waste in environment is considered to be a big problem due to its very low biodegradability and presence in large quantities. One of the solutions for this problem is utilization of plastic waste such as HDPE (High Density Polyethylene) plastic as aggregate in building construction, which is also a partial solution for environmental and ecological problems. Hence this work aims to investigate the effect of using waste HDPE plastic as partial replacement of coarse aggregate by volume in concrete with percentage replacement ranging from 0%, 10%, 20%, and 30%   taking the strength criteria of M25 concrete. This paper also intent to examine the experimental study of flexural strength of RCC beams casted with both conventional and plastic concrete and compare the results also to utilize it for industrial purpose.
