This study was performed to evaluate the strength properties of polymer concrete using recycled aggregate. The compressive strength, splitting tensile strength, flexural strength and pulse velocity of polymer concrete were decreased with increasing the content of recycled aggregate. At the curing age of 7days, the compressive strength was 80.5~88.3MPa, the splitting tensile strength was 9.1~10.6MPa, the flexural strength was 19.2~21.5MPa and the pulse velocity was 3,931~4,041 m/s, respectively. Also, the compressive strength, splitting tensile strength, flexural strength and pulse velocity of concrete using recycled fine aggregate were higher than that of the silica sand.Therefore, these recycled aggregate polymer concretes were estimated for high strength concrete without major problem.
