Deeds and misdeeds of cement composites in waste management
This paper considers the properties of cement composites used as an engineered barrier against the release of radionuclides in repositories for the storage and disposal of radioactive waste. After a discussion of the leaching process and the diffusion mechanism responsible for the release of soluble elements such as caesium, physical factors are analysed, in particular the effect of the water/cement ratio on porosity and compressive strength. Factors affecting leaching, including the effects of flow water, PCO(2) and pH, are also analysed.
