The corrosion of reinforcing and prestressing steel in concrete structures caused by stray currents.  The history of stray-current corrosion, sources, mechanisms, effects on structures, detection and mitigation. 

This technical committee report reviews the corrosion of reinforcing and prestressing steel in concrete structures caused by stray currents. It provides information on the history of stray-current corrosion, the sources of stray currents, the mechanism of corrosion, the effects on structures, and detection and mitigation of stray-current-induced corrosion on steel in concrete. Also covered are measures taken during the design phase and modeling of the stray-current effects. The report is intended for use by designers of reinforced concrete structures, professionals dealing with electrochemical techniques (e.g., cathodic protection, realkalization, and electrochemical chloride removal), owners of structures with the potential for reinforcement corrosion caused by stray currents, owners of systems that could generate stray currents to concrete structures, and electrical engineers.

Key words: Stray current, AC, DC, corrosion, reinforcement, cathodic protection

Population growth in city centers has spurred the expansion and new construction of direct current (DC) powered transit systems throughout the world1. Despite stringent design criteria, quality assurance and quality control (QA/QC) monitored construction practices and ongoing track maintenance, it is a fact that DC stray current will eventually occur and negatively impact buried and/or submerged metallic structures immediately adjacent and within the transit right-of-way (ROW)2. In combination with other methods to reduce stray current such as high track-to-earth (TTE) resistance values and shorter distances between substations, transit agencies are specifying the welding of reinforced steel structures within their purview such as retaining walls and footings, approach slabs, aerial inverts, and bridge abutments to prevent stray current from reducing the design life of surrounding metallic
structures.

Stray current prevention, where do you start? When dealing with stray current from a DC Transit
system it is all about building in “layers” of protection. This begins right from the start of your project through the creation of a design and maintenance guideline, through construction with inspection and testing plans and then through long range testing and maintenance plans.

This standard practice describes appropriate prevention and mitigation measures that can be applied to RC and PC structures that are, or can be, exposed to stray-currents from external sources in order to minimize or eliminate stray-current corrosion. This standard practice addresses only steel corrosion related issues, and does not deal with issues of safety and hazards to people or structures associated with DC and AC voltages; these are covered in national standards and regulations, such as EN 50443 and EN 50122-1.
