• Abstract:
  The corrosion of reinforcing steel in concrete is the leading cause of deterioration for reinforced concrete structures, especially bridges exposed to external chlorides. Practitioners and researchers have evaluated and implemented various technologies to combat this problem, including the use of high-performance concrete, chemical corrosion inhibitors, sealers and barriers, and alternative reinforcement. This synthesis project addressed the latter, specifically the use of alternative reinforcement (e.g., fiber-reinforced polymer (FRP) reinforcement, epoxy-coated steel, stainless steel, galvanized steel, etc.) to extend the service life of bridge structures subjected to external chlorides from marine environments or from de-icing salt applications. The primary goals of this project were to (a) review and synthesize published literature, (b) review and synthesize current DOT practice, (c) identify gaps in the current knowledge and state of practice, and (d) provide guidance, based on current knowledge, on how to evaluate and select alternative reinforcement for bridges subjected to external chlorides.
