Abstract
Plastic is used as a polymer substitute for natural materials. It has become an essential aspect of our lives and there was a considerable intensification in the production of plastic in the last few decades. This research aims to evaluate the possibility of using granulated plastic waste material to partially substitute for the fine aggregate in the concrete specimen. In this M30 grade, concrete design strength of mix ratio of 1:1.3:2.44 and 0.42 w/c ratio were used. Five different percentages (0%, 10%, 20%, 30%, 40%) of recycled polypropylene plastic granules waste were used to replace the fine aggregate and in addition to this GI wire fibre, 2% by weight of concrete was added to improve the mechanical properties of concrete. GI wire fibre can be used as a low-cost alternative to steel fibre in concrete. The physical properties test was conducted on cement, fine aggregate, coarse aggregate and plastic granules. The workability and density were improved by the addition of plastic granules. The compressive and split tensile strengths for the specimens were determined to find the optimum percentage of recycled polypropylene plastic (PP) granules. The test result revealed that the compressive strength increases upto 20% and tensile strength were increased by 10% compared to the normal concrete.
