• Abstract:
  University of South Florida and FDOT researchers hypothesized that galvanic coupling between the galvanized steel duct and the steel strands of bridge members could be one of the mechanisms behind hydrogen production – which accelerates the embrittlement of steel. The objective of this project was to identify the conditions that promote hydrogen production that lead to galvanic coupling and identify the consequences of galvanic coupling between post-tensioned steel and galvanized ducts.
