This standard addresses corrosion of reinforcing steel in concrete, a serious problem throughout the world in parking structures, bridges and roadways, buildings, sanitary and water facilities, marine structures, concrete pipe, storage facilities, and other structures. This corrosion is directly attributable to the presence of significant amounts of aggressive substances at the steel surface. This standard provides procedures to control corrosion of conventional reinforcing steel in Portland cement concrete structures through the application of chloride extraction or realkalization. These electrochemical techniques are related to the use of impressed current cathodic protection of steel in concrete, as described in NACE SP0290. PRINTED HARD COPIES REQUIRE A MINIMUM OF 7-10 DAYS FOR PROCESSING BEFORE SHIPPING.
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.
