Corrosion of reinforcing steel in concrete has produced a problem of catastrophic proportions in the highway field. Bridge decks in the snow belt areas of the country, subject to heavy application of deicer salts in response to the public's demand for year-round bare pavements, frequently start to show signs of severe deterioration after only a few years of service. A wide variety of techniques for retarding or preventing corrosion of reinforcing steel and subsequent potholes in bridge decks have been tried, with varying degrees of success. It appears that the time is ripe for a synthesis and evaluation of these methods in order to properly assess the current status of ameliorative actions and to indicate those areas requiring further investigative effort.
Corrosion of reinforcing steel in concrete is not limited to bridge decks. Examples of reinforcement corrosion in a marine atmospheric environment are cited.
