Thaumasite form of sulfate attack (TSA) in cement-based materials frequently occurs from transportation and hydraulic engineering in western China. The damage and concealment from TSA in cement-based materials are greater than those of conventional ettringite type and gypsum type sulfate attack. In this review, the physical and chemical properties of thaumasite were summarized, and the methods for characterizing thaumasite were also represented. Meanwhile, the different mechanisms of thaumasite formation and affecting factors of TSA were analyzed. The prevention and suppression measures of TSA were introduced. In addition, some aspects for future studies on TSA were also discussed.
