(a) A partially reacted C4AF particle surrounded by hydrated component phases from the electron-density tomogram of the neat PC paste. The different phases and a line to show the electron-density values are also shown. (b) Electron-density values corresponding to the yellow line in (a), with horizontal lines showing the average values of the electron densities obtained for the component phases using ten different particles, data from Table 3[link]. It clearly shows, as an example, how phase 5 encloses the unreacted fraction of the C4AF particle. From the electron-density value and its spatial arrangement, phase 5 is concluded to be Fe–Al siliceous hydrogarnet.
