Abstract:

The development of a ionic diffusivity-porosity relation for cement paste, soundly based on microstructure, along with future developments in this area, are discussed. The importance of such relations for sulfate attack and other mechanisms of deterioration in concrete, as well as for models of the chloride diffusivity of concrete, are outlined.
