• Abstract:
  Thousands of Florida bridges have steel-reinforced concrete piling foundations standing ; in salt water. Over time, chloride ions in the water can migrate through the concrete to ; attack the steel inside. The Florida Department of Transportation (FDOT) has implemented ; designs that better protect the steel. However, many structures were built before the new ; standards and, as such, are more susceptible to corrosion. Steel reinforcement has been ; studied extensively in the section of the pile just above the water line, the so-called splash-evaporation zone, where salt buildup is greatest. ; The portion of the structure below the water line ; has been less studied, but this area can still be a ; site of steel degradation.
