Determining the Effect of Changing Relative Area on the Galvanic Corrosion Rate of Contacting Dissimilar Metals/Materials
The research objectives are to: (1) Conduct accelerated laboratory testing to predict the impact of changing the relative surface area on the corrosion behavior of contacting dissimilar materials under conditions commonly experienced in Florida Department of Transportation (FDOT) concrete bridge structures (focus on steel/stainless steel, CFRP/stainless steel). (2) Provide specific recommendations for inclusion in the Standard Specifications and Structures Design Guidelines on acceptable quantities/ratios of each material that can be placed in electrical contact with each other as reinforcement in a concrete bridge. (3) Review limitation in the FDOT Structures Design Guidelines on using CFRP and Stainless-Steel in the same element for a target service life of 75 to 100 years.
