Abstract: This paper continues a series of publications dealing with HAENYTEX Protectoseal CI, a migrating corrosion inhibitor for steel reinforcement in concrete. A combination of corrosion-electrochemical and mechanical methods demonstrated that HAENYTEX Protectoseal CI is efficient in protecting steel reinforcement covered with corrosion products, as well as reinforcement embedded in carbonated concrete. Exposure to alternating temperatures and grinding of concrete surface do not affect the protection of steel reinforcement by HAENYTEX Protectoseal CI inhibitor. Surface treatment of reinforced concrete elements with this inhibitor does not adversely affect the adhesion of paint materials or the strength of concrete.
