Mechanism and Preventive Technology of the Thaumasite Form of Sulfate Attack on Cement Mortars

Keywords： cement mortar

The deterioration mechanism of thaumasite towards cement or concrete structure and the deterioration pattern of in-situ construction caused by the formation of thaumasite were studied in this paper. To improve the TSA (the thaumasite form of sulfate attack) resistance, the cement type, water to cement ratios, the mineral admixture and the circumstance factors should be taken into consideration.
