Abstract: A series of corrosion tests on fiber reinforced cementitious composites containing a reinforcing steel bar were carried out in order to investigate the influence of the fiber mixed with concrete on durability for corrosion of the reinforced concrete. Two types of fiber reinforced cementitious composites were tested. One was FRC(only polyethylene fiber was mixed) and the other was HFRCC (polyethylene fiber and steel cord were mixed together). They were compared with plain mortar (Mortar). Items of examined durability performance were the time of corrosion initiation, the corrosion area ratio, corrosion depth, and the amount of corrosion rust. As a result, it was shown that the order of the durability performance was HFRCC, FRCC, and Mortar. It might be because HFRCC has an effect of sacrifice corrosion of steel cord fiber.
