Performance and Effect by Temperature of Aluminum Panel Anodes on the Cathodic Protection of Concrete Railway Bridge

It is attracted that cathodic protection method (CP) is effective in the remedy of rusted rebars, regardless of amount of salt in concrete. The aluminum galvanic anode is one of CP. Rebar potential, current density and temperature were measured at concrete rail way bridge with aluminum panel. Analysis and discussion were given to the effect by temperature shift for rebars potential, neither incident affected for depolarization by it. And, measuring time with off potential for measuring of depolarization was appropriate time.
