Abstract:

Reinforced concrete bridges on Oregon’s coast are exposed to chloride ions from marine salt that penetrate into the concrete and cause the reinforcing steel to corrode. The corrosion causes the concrete to spall from the bridge and also reduces the cross section of the steel bars. Repairs include removing the damaged concrete and rust, replacing the badly corroded steel, restoring the dimensions of the beam, and applying cathodic protection to stop further corrosion. Repair and mitigation is expensive, but if left unchecked, the structural capacity of the bridge is diminished. In extreme cases, the bridge is replaced.
