Concrete cathodic protection systems and services are designed to address corrosion problems in steel reinforced concrete. The major cause of corrosion in such structures is the presence of salt resulting from the application of de-icing chemicals, exposure to seawater, or the use of contaminated aggregate in the original concrete mix. When steel bars in concrete corrode, the formation of rust causes high internal pressures and tensile stresses are exerted on the surrounding concrete. Cracks develop, leading to delamination and spalling of the concrete.
Structural Corrosion Prevention
Cathodic protection effectively stops the corrosion process and has been determined by the Federal Highway Administration to be the only rehabilitation technique able to prevent further corrosion in such structures regardless of the salt content in concrete. Cathodic protection of reinforced concrete structures has also been endorsed by the American Concrete Institute (ACI), AASHTO-AGC-ARTBA Task Force 29 and the National Association of Corrosion Engineers (NACE International).
