Abstract:The Florida Department of Transportation (FDOT) is responsible for the maintenance of thousands of concrete structures that are exposed to or situated in salt water. Considering the significant cost of each of these structures, FDOT would like a 75-year span before any major repair is needed. These structures are invariably reinforced with steel, which is subject to corrosion if chloride ions from the marine environment can penetrate the concrete, so the diffusion rate of chloride ions through concrete is a critical durability issue.
