Abstract: This paper represents results of strength tests conducted on concrete containing flakes of waste metalized plastics. The feasibility of post consumer plastic waste (PCMPW) was determined on the bases of tests results of compressive strength and split tensile strength. Ever increasing generation of PCMPW has raised littering issues and has become one of the major sources for landfills. The objective of the test program was to check the feasibility of PCMPW as concrete constituent and possible way of mitigating the environmental impacts occurring from insufficient and unsafe management of PCMPW. The strength tests were performed with three sizes of PCMPW in flaks and fiber form. PCMPW was added in the mixes with 0%, 0.5%, 1%, 1.5% and 2% by volume of concrete mix. Test results reveled that strengths reduced with increased PCMPW flakes contents. However, up to 1% of addition of flakes the strength reduction was negligible for all flak sizes. Moreover, the PCMPW fiber with 1mmx17mm size improved the split tensile strength. Experimental results of compressive –split tensile strength were correlated by a standard analytical model and exhibited good agreement with the experimental results. Such concrete could be utilized in pavements, substructural components and in non-structural members.
