The Effects of Polypropylene Wastes on the Compressive Strength of Grade 25 Concrete

Abstract

The effect of polypropylene waste on the compressive strength of grade 25 concrete was studied. This was due to the increased problem of environmental pollution which may lead to flooding these wastes are causing in our environment. The research used the experimental methods in carried out the study. The polypropylene were pulverized to sand particle sizes and dosed at 5 %, 10 %, 15 % and 20 % by weight as partial replacement of sand in grade 25 concrete, cured for 7 days, 14 days, 21 days and 28 days respectively. The results reveal that polypropylene can be substituted with sand in concrete up to 15% by weight with a negligible decrease of 3.7 % of compressive strength when compared to the control concrete. This depicts that polypropylene can be used in producing sustainable concrete.
