Abstract: Aspects of physical sulfate attack of concrete are discussed. As physical sulfate attack involves the migration of electrolyte solutions, the prevalence of sulfate and carbonate evaporate minerals in the environment and their effects on the environment are summarized. The interaction of these minerals with porous media is described and this is accompanied by a description of the mechanism driving their migration. Forms and consequences of sulfate attack are briefly reviewed to provide a context for the phenomena involved in physical sulfate attack. The nature of the processes involved in physical sulfate attack is discussed as are the mechanisms which result in damage. In particular, the effects of crystal growth pressure and hydration pressure are considered.
