Reaffirmed (with editorial changes) in 2019. Presents corrosion control guidelines that are applicable to existing atmospherically exposed structures made of concrete conventionally reinforced with carbon steel. These guidelines should be used primarily when repair or rehabilitation is being implemented because of deterioration resulting from the corrosion of steel reinforcement. Includes sections on Periodic Inspection and Routine Maintenance of reinforced-concrete structures (site survey, structural survey, repair options), Assessment of Reinforced Concrete Structures, and Corrosion Control Techniques and Repair Strategy. Corrosion control techniques that are described include surface treatments, removal of concrete, and electrochemical treatments, including ECE, ER, and cathodic protection.
New in 2019!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.
