Recent construction activities and maintenance of marine facilities have been accelerating to keep up with rapid economic growth in Korea. Marine concrete structures are to salts and chloride from ocean environments. The corrosion of reinforcement steel caused by chloride-penetration into concrete may severely affect the durability of concrete structures. the objective of this research is to develop a durable concrete by investigating the resistance of various corrosion protection systems utilizing different water/cement ratio, silica fumes, corrosion inhibitors, etc. A two-year verification test on various corrosion protection system has been doing in the laboratory. Corrosion investigations on reinforcement steel are now under progress for more than 63 concrete specimen. Corrosion-related measurements include microcell corrosion current.
