Abstract

Researching on corrosion protection technologies for steel pipe piles have been under operation by the exposure test using real pier in HASAKI since 1984. This paper is reporting the durability and corrosion protection performance of concrete cover method obtained from the exposure test. Deterioration of concrete cover was differed by materials and environments. Concrete cover in splash zone and marine atmospheric zone after 25 years was spalled off and fracture of reinforcing bar due to corrosion was occurred. On the other hand, concrete cover in tidal zone was sound. Despite the chloride ion concentration at steel surface in concrete was about 20 kg/m3, steel had not been corroded. It is considered that diffusion of oxygen into the concrete was limited to the level that could not generate the steel corrosion.
