Sacrificial anodes in concrete patch repair
High performance cementitious concretes or mortars and bonding agents developed for use as patch repair materials for corrosion damaged concrete often have high resistivities that inhibit the performance of sacrificial anodes located within patch repair areas.

| description | High performance cementitious concretes or mortars and bonding agents developed for use as patch repair materials for corrosion damaged concrete often have high resistivities that inhibit the performance of sacrificial anodes located within patch repair areas. A method of repair is disclosed that comprises removing the corrosion damaged concrete to expose steel and form a cavity to receive high performance concrete repair materials and forming within the parent concrete exposed in this cavity a smaller distinct cavity for assembling a sacrificial anode assembly and placing within this anode cavity a pliable viscous ionically conductive backfill and a sacrificial anode and an activating agent to form a sacrificial anode assembly and connecting the anode to the steel and covering the anode assembly in the anode cavity with a repair material to restore the profile of the concrete structure. In this arrangement a high resistivity repair material promotes the flow of protection current to steel in adjacent contaminated concrete that is at risk of corrosion |
