Si K-edge NEXAFS analysis of 7-day-hydrated C3S particles in the presence of CaCl2: (a) single image of one particle taken at 1855 eV, (b) Si K-edge NEXAFS spectra of the line-scan indicated in (a), (c) single image of another particle taken at 1855 eV, (d) image contrast mapping corresponding to (c), (e) selected areas in the image contrast map enlarged partly from (c) for the NEXAFS spectra, and (f) Si K-edge NEXAFS spectra taken from the different locations indicated in (e).
