Test method to evaluate coatings w/conductive carbon pigmentation as Cathodic Protection (CP) anodes on atmospherically exposed reinforced concrete. Anode coatings are not to provide a protective barrier. HISTORICAL DOCUMENT
This standard provides a test method to evaluate coatings containing conductive carbon pigmentation for use as an anode on atmospherically exposed reinforced concrete. These coatings are commonly applied to steel-reinforced concrete surfaces for the purpose of supplying cathodic protection (CP) current to the embedded steel. The coating systems used for this purpose are intended to serve as an anode material and are not intended to provide a protective barrier coating to the concrete. This standard is intended for use by consultants, suppliers, and users of CP systems intended to reduce corrosion of embedded steel in atmospherically exposed reinforced concrete. This standard is expected to be used primarily to qualify coatings containing conductive carbon pigmentation as an anode material, rather than as a quality control procedure.
Key words: Reinforced concrete, atmospheric, cathodic protection, conductive carbon pigmentation, coatings, electrochemical test, developed by technical committee TG 045.
