In the original article, there were some errors in Figures 4, 8–11 as published. The tobermorite contents of sample 90d-FS-1 and sample 90d-FS-2 were plugged incorrectly in the line plots (Figure 8 and Figure 11). The mass absorption coefficient (MAC) was not corrected when calculating the phase compositions of the sample 180d-FS-1 (Figures 4, 8–11). The corrected Figures 4, 8–11 and their captions appear below.

The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way because these changes are relatively small. The original article has been updated.
