Abstract:
Current experience with steel corrosion in concrete structures exposed to Norwegian marine environment is outlined and discussed. It is not the disintegration of the concrete itself, but rather electrochemical corrosion of embedded steel, which poses the greatest threat to the long-term performance of concrete structures in this environment. If proper concrete quality and cover thickness are combined with proper quality assurance and quality control, it appears that reinforced and prestressed concrete can remain serviceable with little or no maintenance for a long period of time even in this most harsh and aggressive marine environment.
