The objective of this study is to determine the maximum usage of polystyrene beads from solid waste as aggregate replacement material in concrete for the purpose to recycle solid waste, and thus diverting waste from being disposed in landfills. Different ratios of polystyrene were used; 25%, 50%, 75%, and I00% were mixed with gravel and sand of the same cement content and water cement ratio. A standard concrete mixture was provided for control concrete standard. Concrete cubes with dimensions of I00 mm xI00 mm xI00 mm were cast according to British Standard (BS 1881 part 116:1983). The engineering parameters studied were slump test and absorption test in comparison to the control concrete. The results showed that the absorption of concrete with different ratios of polystyrene in comparison to the control mixture reduced up to 82.05 % for I00% replacement of polystyrene. While the workability of the concrete mixtures was increased with the increasing of polystyrene beads with average of (medium).
