Abstract

Sacrificial (galvanic) anode and hybrid cathodic protection systems have recently become more prevalent in the concrete remediation and protection industry. The galvanic anode technologies have existed for over a decade and considerable research has been undertaken abroad to assess the performance of various systems. The hybrid systems have been developed in recent years. Uncertainty exists surrounding key performance parameters of such systems as well as robust independent guidelines for selection and design. A review of the available literature has been undertaken to identify what is currently understood about these technologies, their theoretical performance parameters, and examples of their actual performance in real life applications. From this basis, the authors also present a framework for the future development of adequate guidelines for the application of sacrificial anode and hybrid cathodic protection systems within Australia.
