Experimental Study on Recycled Waste Plastic Material in Concrete

The demand and cost of natural aggregates is increasing day by day due to its non-availability. Aggregates are very important for construction projects, however due to maximum consumption they are getting depleted. Hence suitable alternative materials like recycled plastic aggregates made up of purely waste plastic materials are used as a replacement for these natural aggregates. Utilization of these recycled plastic aggregates (RPA) in concrete helps in disposal of plastic waste and thereby helps in conserving the natural resources and the environment. In the current study, recycled plastic coarse aggregates and recycled plastic fine aggregates in varying percentages of 0, 10, 20 and 30% with the addition of bonding agent were used to partially replace the natural coarse aggregates and fine aggregates in the M30 grade concrete mix design. Concrete was subjected to permeability testing as well as strength tests for its compressive, flexural, and split tensile properties. From the test results it is concluded that desired strength results were obtained for 30% replacement of recycled plastic coarse aggregates and 10% replacement of recycled plastic fine aggregates for M30 grade concrete.
