Corrosion of Steel in Continuously Submerged Reinforced Concrete Piling
The report describes a portion of a broader corrosion study and examines in some detail the aspect of steel corrosion in portions of piling which were continuously submerged for a period of approximately 37 years in sea water. As part of a contract for a new bridge as a replacement of the 37-year old San Mateo-Hayward Bridge which was located in San Francisco Bay, the existing piles from the old bridge were removed. A total of 17 of these piles were inspected for this study by exposing the reinforcing steel. In addition, samples of concrete were obtained so as to determine the contained salt content. Under continuously submerged conditions, it was found that 8 out of 17, or approximately 47 percent of the pilings had heavy corrosion of the steel. The metal loss of the heavily corroded steel was in the character of broad pits that ranged in depth between 0.017-inch and 0.260-inch and averaged 0.114-inch.
