It has been known that durability of mortar is improved by addition of polymer. We assume that the addition of polymer is one of technologies about extension of life-span of concrete. Experimental studies about mechanical property, durability and property of drying shrinkage cracking of concrete added SBR were carried out. As a result, strength of concrete added SBR was the same degree or greater than normal concrete. Carbonation depth was decreased as the ratio of SBR were increased. Relative dynamic modulus of elasticity of the concrete added SBR under on resistance of freezing and thawing test was much the same of normal concrete added an air entraining agent. No cracks had occurred for 55days on drying shrinkage cracking test when SBR were added to 10% weight ratio of cement.
