A case study of a major CP system operating in Australia for 15 years and proposal of a series of changes to current practices which can be considered for implementation in the design, installation and monitoring stages of new impressed current cathodic protection systems in concrete.
Impressed current cathodic protection (CP) for reinforced concrete structures is a proven technology which can provide long term corrosion prevention for marine structures if properly designed and installed. This technology has been applied to large a number of concrete structures in Australia over the past 30 years and it is the technology of choice for many asset owners for the protection of structures susceptible to chloride induced corrosion. While this technology has proven to be highly effective in providing corrosion protection to embedded steel reinforcement in some cases the maintenance and monitoring costs have been relatively high and this is often due to defects during the design and construction stage of the system. The review of performance of many operating CP systems in Australia has led to the conclusion that there are many areas of improvement which can be implemented to optimise the long term performance of impressed current CP systems. The areas of improvement include materials selection design installation and monitoring of CP systems. This paper will provide a case study of a major CP system operating in Australia for 18 years and will propose a series of changes to current practices which can be considered for implementation in the design installation and monitoring stages of new impressed current cathodic protection systems in concrete.

The use of cathodic protection has become the preferred method for mitigating corrosion of steel reinforcement in concrete. A wide variety of both impressed current and sacrificial systems have been effectively used to control the effects of corrosion.

This work seeks to determine the performance of cathodic prevention (CPrev) and cathodic protection (CP) systems applied to cracked concrete in a simulated marine environment.
This paper is based on a case study of cathodic protection of building foundation piles for several buildings installed on top of a landfill in the San Francisco Bay Area.
