CORROSION OF METALS IN ASSOCIATION WITH CONCRETE.

There has been a lack of both a critical review of current information and an assessment as to the areas where further data are needed. Recognizing this need, the Metal Properties Council initiated Project 880-2, 'A Report on the Corrosion of Metals in Association with Concrete. ' This ASTM Special Technical Publication 818 incorporates that report. In the publication the actual magnitude of the problem is investigated, addressing the nature of the problem, an historical perspective, some economic viewpoints, and the nature and type of structures affected. The fundamental mechanisms regarding the corrosion of reinforcing in concrete are covered, including the properties per se of concrete and the specific aspects of corrosion of steel in concrete which are dissimilar from other types of corrosion. Some discussion is then given to factors influencing the rate of corrosion of steel in concrete, methods of measuring the deterioration, and methods of protecting against the deterioration. Finally, current standards are assessed and areas of future work are suggested.
