N2 - For the durability enhancement of port RC structures, corrosion resistant property of three types of stainless steel bars (SUS430, SUS304 and SUS316) in concrete was studied by the exposure tests under marine environment. Results obtained are as follows, i) No corrosion was observed at the sound part on all types of stainless steels under high concentration of chloride ion. Here, the threshold levels for corrosion were estimated larger than 13-14 kg/m3, ii) No corrosion was observed at the small cracked part on all types of stainless steels where the crack width was smaller than 0.5mm. On the other hand, slight corrosion was observed at the large crack regions where the crack width was larger than 0.5mm on SUS 304 and 316. iii) In case that stainless steel bar is applied to port RC structures, the life cycle cost can be lower than the case of carbon steel bar.
