ABSTRACT
Sulfur Polymer Concrete (SPC) is produced from mixing of melted sulfur (modified with polymeric
additives) and aggregates. The main objective of this study is to determine of the optimum amount of sulfur polymer in concrete mix. For this purpose, different amounts of sulfur polymer were mixed with an aggregate. Then the mechanical and physical properties of Sulfur Polymer Concrete including; Compressive strength, Yield point and modulus of elasticity, void of mineral aggregate, unit weight and air percentage and workability of the concrete were studied. Maximum amount of compressive strength (58.6 Mpa) was determined for specimens having 17 percent sulfur and the specimens with 11 and 23 percent sulfur had the minimum values(42.4 and 41.6 Mpa). Therefore, the optimum amount of sulfur was found to be about 17% by weight of aggregates, which is equal to the void of aggregates. Also the compressive strength, Yield point
and modulus of elasticity of this combination were obtained 58.6 (MPa), 52.5 (MPa) and 5.3 (GPa)
respectively. This mixture workability also was better than other treatments.
