Galvanic Corrosion Protection of Reinforced Concrete Structures

Picture for Galvanic Corrosion Protection of Reinforced Concrete Structures
Available for download

Chloride induced corrosion of steel reinforcement in concrete structural elements is a major worldwide problem [1]. Chlorides can be introduced into the concrete via de-icing salts, seawater, high salinity groundwater or sabkha soils [1.2]. This leads to localised breakdown of the normally passive steel reinforcement in the form of pitting corrosion [2].

Galvanic corrosion protection systems have been developed to provide long-term corrosion protection to existing concrete structures suffering from corrosion. Through the partnership and support of structure owners such as Ohio Department of Transportation, Ontario Ministry of Transportation, Florida Department of Transportation and Transport New South Wales these systems have been installed and monitored on bridge decks and substructures for many years. Some of these structures have been monitored for over 20 years. This paper presents the development, installation and 20-year field performance of these galvanic corrosion protection systems and how this real-world performance data can be used to design long-life galvanic corrosion protection systems to extend the service life of reinforced concrete structures.

AMPP SP21520-2023, Acceptance Criteria for Cathodic Protection of Steel in Concrete Structures

Product Number: AMPP SP21520-2023
Publication Date: 2023
$109.00

Historically, NACE SP0290, NACE SP0216, and NACE SP0408 included sets of criteria that needed to be satisfied to indicate that a cathodic protection (CP) system is delivering adequate current to passivate the reinforcing steel or reduce its corrosion current to low and non-destructive levels. These criteria were mostly the same, so the aim of this standard is to set out the essential criteria that each one of the above standards must satisfy in a single document. This allows each of the above standards, which deal with different applications of cathodic protection, to concentrate and expand on aspects that are specific for each application. This standard further suggests techniques that can be employed to estimate the level of protection achieved by a non-compliant cathodic protection method.

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.
