This study aimed to investigate for the first time the utilization of waste compact discs (WCDs) granules in concrete mixtures to replace the fine aggregate by 5%, 10%, 15% and 20 % by weight. The influence of partial replacement of the waste compact discs (WCDs) on the fundamental mechanical and strength properties of the WCDs-modified concrete mixtures were investigated. The properties included workability, bulk density, compressive strength, flexural strength, and split tensile strength. Compared to the control or reference concrete, results revealed that using waste compact discs in concrete mixes mixture improved the workability and the dry density, as well as reducing the compressive strength of concrete containing 10% and 15 % of waste by 15% to 20 %, respectively after 28 days curing. Also, the split tensile strength values of WCDs-modified concrete mixtures were increased by 10% and 12% when the ratio of waste compact discs were 10% and 15 %, respectively after 28 days curing. On the other hand, the leaching test revealed that none of the WCDs constituents was detected in the leachant after 180 days. The findings of this work would form basic information for recycling the waste compact discs (WCDs) in concrete mixes and indicate a potential alternative for diminution the adverse effects on the environment posed by this type of hazardous waste material.
