摘要：
This study is to acquire the confirmation data regarding the cathodic protection and cathodic prevention characteristics for concrete piles in marine bridges and piers exposed to harsh marine environments. It was possible to confirm the performance of cathodic protection by the measurement of potentials and current density the concrete pile specimens applied with zinc mesh sacrificial anode cathodic protection system. The current density for the cathodic protection (CProt) that CP started after a repair of corrosion was higher than that for the cathodic prevention (CPrev) that CP commenced from the beginning of experiment, and 4 hour depolarization potentials were higher in the CPrev system than in the CProt one, and it was confirmed that the CPrev has more protection effect with less protection current, comparing to the CProt.
