Abstract: The application of sodium monofluorophosphate solution as a surface treatment compound on natural carbonated blast furnace slag cement (BFSC) mortar was studied. The treatment was performed on the surface of mortars either at the age of 10-day or after the one-year natural exposure, described as pre- and post-treatments, respectively. The experimental results show that the treatments evidently improved the frost scaling durability of carbonated BFS mortars. The XRD analysis shows the formation of fluorapatite and carbonate fluorapatite in the carbonated matrix. Pore coarsening due to carbonation shrinkage was reduced accordingly.
