• Abstract:
  Many Florida bridges are built of steel-reinforced concrete. Florida’s humid and marine ; environments subject steel in these structures ; to corrosion once water and salt penetrate the ; concrete and contact the steel. Corroded steel ; takes up more space than the original steel, ; resulting in cracked and spalling concrete which ; further exposes the steel, and requires expensive ; repairs and corrosion control techniques. ; The Florida Department of Transportation ; (FDOT) has responded with corrosion prevention ; practices, such as very low permeability concrete ; and increased concrete cover thickness over ; reinforcing steel. This increases initial cost but ; saves money over time, since the bridge’s service ; life is significantly extended. So, it is important ; to understand how a specific design can increase ; service life for the specific environment in which ; the bridge will be built.
