Abstract

Permeable concrete is an environmental friendly concrete used in pavement structures which reduces the water runoff and helps in maintaining the ground water level. The objective of this study is to scrutinize and inquire the change in engineering properties of permeable concrete by addition of granulated waste plastic. The waste plastic used in this permeable concrete mix is in the form of granules having size between 2 mm and 3 mm. These were added in different percentages – 25%, 50%, 75% and 100% as a partial replacement to fine aggregates. Tests were conducted on fine aggregates, coarse aggregates, cement and modified mix (waste plastic mix permeable concrete) to investigate their physical strength, mechanical strength and the rate of infiltration of water. The testing included the tests for Loss angel's abrasion value, Impact value, Specific gravity and Water absorption for the aggregates, and fineness, consistency, compressive strength and permeability tests for the concrete. Concrete cubes were casted with different proportions of the materials and were tested after 7, 14, and 28 days for the strength. Cylindrical samples were also cast and were tested after 24 hours to determine the infiltration rate of the concrete. It was found that the compressive strength and permeability of permeable concrete starts decreasing significantly only after 25% replacement of fine aggregates by granulated waste plastic. For a 25% replacement, no significant decrease in strength or permeability was observed
