Abstract

Large quantities of carbon steel are likely to be used in repositories for intermediate and low level wastes both for containment and structural purposes. In many cases the environment surrounding the steel will be cementitious, consisting of structural concrete, cemented waste or cement grout backfilling. Because these materials have a finite permeability, it is inevitable that the steel will be in contact with water and hence subject to some corrosion. Initially this water will be that used to mix the cement, but in later years it will be altered by the natural waters which permeate the repository site. This project investigated: - the rate of anaerobic corrosion of steel in concrete; - the nature of the corrosion products formed on carbon steel which is embedded in concrete under anaerobic conditions, and - the effect of hydrogen over-pressures on the rate of corrosion in simulated cement pore-water electrolytes. All experiments were carried out under ambient conditions (20-30 C).
