Experimental Study On Plastic Waste As A Course Aggregate For Structural Concrete

The use of plastic is increasing day by day, although steps were taken to reduce its consumption. This creates substantial garbage every day which is much unhealthy. The suitability of recycled plastics as coarse aggregate in concrete and its advantages are discussed here. In this project, Plastic Coarse Aggregates (PCA) and steel fibers were used as replacement of Natural Coarse aggregate by different percentage of plastic aggregate for making concrete of M-25 grade, with w/c ratio 0.48. The study involves replacement of natural coarse aggregates by 0, 15 and 30 percentage of PCA. The steel fibers are used 1 to 3 percent by weight of cement. OPC-53 grade cement was used for making concrete. The waste plastic of HDPE (High density poly Ethylene) is collected from Agriculture waste, E-waste. The study also involves casting cube, beam and cylinder by using M-25 concrete with varying percentage of PCA and then testing compressive strength, flexural strength and Split tensile strength respectively. Also, from this study Optimum percentage replacement of natural aggregate by PCA was found out and that can be used in structural concrete
