초록
This study has been conducted to confirm the effect of sacrificial anode cathodic protection system for 90 days toprotect corrosion on pier that is located in Korea. The cathodically protected structure was a slab and a pile cap. Before theconstruction of cathodic protection system, the macrography was carried out. As a result of the macrography, many corrosiontraces were confirmed in this structure. The trace was mainly focused on joint and zones that concrete cover was eliminated. To apply the cathodic protection system, many onsite techniques have been adopted. In addition, to confirm the inner state ofsteel in concrete properly, a corrosion monitoring sensor (DMS-100, Conclinic Co. Ltd) has been applied. Test factors werecorrosion & cathodic protection potential, 4 hour depolarization potential, resistivity and current density. After 90 days from theinstallation of cathodic protection system, it could confirm that proper corrosion protection effect was obtained by consideringthe result of tests.
