Abstract:Maintenance costs for concrete structures that are exposed to de-icing salts and marine environments represent large expenditures for owners as a results of corrosion of steel in concrete. To solve this problem, the US Federal Highway Administration sponsored a comprehensive program todevelop a new alloy to be used as a sacrificial anode for reinforced and prestressed concrete structures. Based on intensive studies of existing metals and alloys, a new alloy was developed to overcome the observed deficiencies in the existing materials. The new aluminum-zinc alloy can be thermally sprayed on concrete surfaces to protect steel from corrosion in chloride contaminated concrete. This paper presents the results of both laboratory testing and field installation of this new alloy.
