Abstract
Plastic pollution is one of the greatest causes of global warming. Disposal of large quantity of plastic waste products causes environmental & health issues .This report will discuss a solution to plastic pollution by conducting to recycle the plastic and reuse in concrete, so the waste plastic is recycled into plastic aggregates. This paper aims to enhance the concrete mechanical properties by replacement of natural coarse aggregate with recycled plastic aggregates and by adding polypropylene fibers in combination with high performance cement as a partial replacement of cement. This both combinations in concrete gave excellent values of compressive strength and tensile strength. Replacement of coarse aggregate weight by 10%, 20%, 30%, 40%, 50% of recycled plastics and for each replacement percentages polypropylene fibres of 0.1%, 0.2%, 0.3%, 0.4% with partial replacement of cement were conducted. In literature reported that the addition of recycled plastic causes the reduction of strength due to poor bonding between concrete and plastics, to overcome this problem the addition of polypropylene fibres which has a good bonding property will improve the concrete strength were added. Result shows that 35% replacement of natural aggregates with plastic aggregate achieves the maximum strength of concrete.
