Indian Concrete Journal - ICJSummary: An experimental exploration was done to study the impact of recycled plastic waste granules as partial substitute for fine aggregate in normal-strength concrete. The volume of M-sand in conventional concrete proportioned for M30 grade was altered with 5, 10 and 15 percent plastics granules. Furthermore, 10 % by-weight of total aggregates in the plastic aggregate mixture was replaced with waste glass cullet was also investigated. The strength related properties of the plastic aggregate concrete showed decrease with increase in plastic replacement levels. A maximum of 13 % loss was observed in compressive strength and a 6.5 % loss in flexural strength. The modulus of elasticity property encountered a maximum loss of 4.5 % when compared to the control conventional mixture. The maximum slump loss of about 14 % was observed in the mixture with 15 % plastic aggregate concrete mixture. The dry unit weight of the plastic mixtures showed reduction in the range of 0.4 to 1.4 %. Whereas, the crushed glass incorporated plastic aggregate concrete mixtures performed in the acceptable range comparatively. The results validate the use of plastic granule aggregate as partial replacement for fine aggregate in the production of lower grade concretes for non-structural members.
