Abstract:

Bridges on Oregon’s coast must withstand the corrosive marine environment. Many reinforced concrete bridges, some having historical significance, have been damaged by corrosion. In the late 1990s, the Oregon Department of Transportation (ODOT) began using impressed current cathodic protection (ICCP) and, to a lesser extent, sacrificial anode cathodic protection (SACP) to prevent corrosion damage.

The humectants chosen for this study, LiNO3 and LiBr, are salt solutions that are sprayed onto the zinc surface of the bridge. Laboratory studies were initially conducted to evaluate the performance of each humectant. Samples were tested in a controlled environment under several climatic conditions, including high and low relative humidity.
