Abstract:
1. A method of protecting steel in a reinforced concrete construction with an anode and a viscous, pliable and ionically conductive backfill contained within a cartridge, the method comprising the steps of: mechanically forming at least one cavity in the concrete; selecting the ionically conductive backfill such that the ionically conductive backfill remains pliable and viscous for at least 48 hours following storage of the ionically conductive backfill within the cartridge; injecting the ionically conductive backfill from the cartridge into the at least one cavity; inserting the anode into the at least one cavity with the anode comprising a sacrificial metal element less noble than steel; and passing a current from the anode to the steel in the concrete to protect the steel in the reinforced concrete construction.
