Corrosion of reinforcing steel is a leading cause of concretedeterioration such as spalling cracking and delamination of reinforced concrete structures.This paper describes a new self-powered two stage anode system used to control corrosion in reinforced concrete structures. This two-stage system combines the high level performance of an impressed current cathodic protection system (ICCP) with the long-term maintenance-free capabilities of an alkali-activated galvanic cathodic prevention system (GCP).Impressed current and galvanic corrosion protection systems are beneficial in extending the service life ofchloride contaminated and damaged concrete structures. ICCP systems are typically powered by an outside DC power source such as a transformer/rectifier and can provide a lifetime of corrosion protection if suitably maintained. Galvanic systems use metals such as zinc that are more electronegative than steel in concrete. Galvanic systems are often used when simplicity is desired as there is no power supply involved and maintenance is minimal.This single-unit second generation hybrid system does not require complex wiring or an external DC power supply. Once installed the anode automatically provides an initial phase of high charge density that passivates active corrosion (Stage 1). The anode automatically switches to provide long-term maintenance-free galvanic protection (Stage 2) when the impressed current stage is complete.As a result this self-powered two-stage system provides a long-term maintenance-free corrosion protection alternative for reinforced concrete structures.
