Zinc galvanic anode GSC

for rebarlaminated

A GACP system utilises anodes which generate a natural DC current to suppress the corrosion of the steel in concrete. GSC Super Anodes are specifically designed to inhibit corrosion of concrete reinforced structures using GACP. The anodes are typically embedded within the concrete or repair mortar and are electrically connected to the reinforcement by using galvanised ties. As zinc is less noble than steel it means that the anode has a more electronegative potential than the reinforcement steel. This makes the zinc the anode and the steel reinforcement the cathode. Current will flow from anode to cathode inhibiting rebar corrosion thus avoiding concrete cracking and spalling in the presence of chloride salts within the concrete . The Zinc anode will generate an electrical field whilst immersed in the electrolyte allowing protective current to be discharged to the steel within the anode area of influence. This allows a relatively small amount of anodes to be distributed within the structure thereby reducing manpower requirements and costs if desired, performance can be monitored easily by on-site personnel
