Recently, safe disposal of post-consumer waste polymers has turn out to be a serious problem because of its non-biodegradable properties and large application. Due to user pleasant properties such as durability, low density, strength and low cost etc. the application of polymer waste annually has been growing steadily. Along with increasing in plastic wastes being disposed into the environment, the problems of disposal must be overcome. Being a very lightweight material, it is not possible to use waste polymers for land filling, which need large land space area. In contact with waste plastics, the land loses its fertility which also leads to environmental pollution. Incineration is another disposal method, but locating sites for new incineration facilities have led to considerable air pollution. The use of polystyrene polymer is increasing day by day with economic growth. However, this polystyrene polymer is not decomposed and it is causing a serious environmental problem by growing as a solid waste. That’s why an alternative process of recycling such materials as a coarse aggregate by partial use in concrete may reduce solid waste and made lightweight concrete and find the physical and mechanical properties of this concrete. The conventional coarse aggregate in concrete will replace with 0%, 10%, 20% and 30% (by weight) of Expanded polystyrene (EPS)and the ordinary Portland cement will replace with Silica Fume as the same percentage. A mix proportion of M40 and M50 with water/cement ratio ranges from 0.35 - 0.56 will use and polystyrene granules will cast, and specimens will test at 7th and 28th days after natural curing.
