Styrofoam polystyrene was widely used in food and manufacturing production as packaging tools to absorb vibration during handling and transportation process. Due to light weight characteristics, it has potential to serve as aggregates replacement of coarse aggregates. This project reports the results of an experimental investigation into the properties of hardened concrete containing expanded polystyrene beads by studying characteristic strength of concrete. The beads are used as part of aggregate replacement in the mixes. The project includes study of characteristic properties of EPS concrete with partial replacement of coarse aggregate with equal volume of expanded polystyrene at levels of 0 % , 5 % , 10 % , 15 % , 20 % , 25 % , and 30 % . Its properties are compared with those of conventional concrete i.e., without EPS beads. The properties of concrete are mainly influenced by the content of polystyrene beads in the mix.
