In this paper,a 10% sodium monofluorophosphate solution was used as a surface treatment compound,and its effect on the durability of carbonated blast furnace slag cement(BFSC) mortar were investigated.The treatment was performed on the surface of mortar either at the age of 10 d or after the one-year natural exposure,described as pre-and post-treatments,respectively.The microstructure of the mortars was severely damaged after carbonation attack.With treatment,however,it was found that the microstructures of carbonated matrixes have been improved accordingly.The results show that the treatments evidently improve the frost scaling durability of carbonated BFSC mortars.
