NACE SP21427-2019 “Detection and Mitigation of Stray-Current Corrosion of Reinforced and Prestressed Concrete Structures”

Picture for SP21427-2019 “Detection and Mitigation of Stray-Current-Induced Corrosion of Reinforced and Prestressed Concrete Structures”
Available for download

HISTORICAL DOCUMENT. This NACE International standard practice establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (DC) and/or alternating current (AC) from external sources on steel reinforced concrete (RC) and prestressed concrete (PC) structures or structural elements. The standard practice offers guidance for the design of concrete structures that may be subject to stray-current corrosion; the detection of stray current interference; the selection of protection measures; and the selection of mitigation methods.

HISTORICAL DOCUMENT. This NACE International standard practice establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (DC) and/or alternating current (AC) from external sources on steel reinforced concrete (RC) and prestressed concrete (PC) structures or structural elements. The standard practice offers guidance for the design of concrete structures that may be subject to stray-current corrosion; the detection of stray current interference; the selection of protection measures; and the selection of mitigation methods.

 

The standard practice is intended for use by designers of RC and PC structures, professionals working with electrochemical techniques (e.g., cathodic protection [CP], realkalization, and electrochemical chloride extraction [ECE]); owners of structures with the risk of reinforcement corrosion caused by stray currents; owners of systems that could generate stray currents to concrete structures; engineers; and other interested parties.

 

 

Key words:alternating current (AC), cathodic protection (CP), concrete, corrosion, direct current (DC), electrochemical chloride extraction (ECE), electrochemical techniques, grounding, impressed current cathodic protection (ICCP), IR-free potential, NACE Publication 01110, NACE SP0177, NACE SP0290, prestressed concrete (PC), potential interference, rail transit, realkalization, reinforcement corrosion, sacrificial anodes, static stray currents, steel reinforced concrete (RC), STG 01, stray currents, Stray Current Corrosion, stray-current mitigation, telluric currents, TG 356.

One of the key factors affecting ship perfor­mance, particularly fuel consumption and associated GHG (Green House Gas) emis­sions, is the degree of biofouling on the immersed hull and propeller(s). Rates of biofouling accumulation vary considerably, depending on the suitability, age and physi­cal condition of the coating system(s) ap­plied to the hull, the voyaging, anchoring and lay up patterns of the ship, and the geo­graphical regions where these take place.
