Control of Steel Corrosion in Chloride Contaminated Concrete Through Aron Wall Surface Coating

Abstract

This paper presents extensive test data on the ability of, ARON WALL, an acrylic rubber type coating in fulfilling two important functions: preventing chloride intrusion and ingress of water, air and other destructive agents. Tests on coated and uncoated reinforced concrete prisms containing various amounts of added sodium chloride and exposed to sea water are reported. The results show conclusively that ARON WALL coating prevents the intrusion of air, water and chloride ions, and provides excellent protection to steel in chloride contaminated concrete while maintaining its adhesion to concrete, integrity and continuity.
