Anotácia

This specification covers filled epoxy-coated seven-wire prestressing steel strands with protective fusion-bonded epoxy coating applied by the electrostatic deposition method. This specification also covers relaxation loss limits for filled epoxy coated strands. Prestressing steel strands shall be free of contaminants such as oil, grease, or paint. Steel strand surfaces shall be cleaned to meet coating requirements, such as coating thickness, coating continuity, coating adhesion, coating composition, and coating bond with concrete or grout. Smooth or grit-impregnated coating shall be applied by the electrostatic deposition method or other method that will meet the coating requirements. Pullout tests shall be performed three times annually or maybe repeated if the coating failed to meet the requirements.
