A sacrificial magnesium anode cathodic protection system has been installed to provide corrosion protection to an underground steel reinforced concrete structure. The system was installed to abate the development of corrosion on steel reinforcing bars that were left exposed to soil and water as a result of concrete placement difficulties.

The system has been in service for a period of five months and excellent performance. This paper reports on the design, installation, materials used, and system performance for the period in service.
