(a) Unreacted spherical FA particle within hydrated component phases from the electron-density tomogram of the PC–FA blend paste. The component phases and a line to show the variation of the electron density values are also displayed. (b) Electron-density values corresponding to the highlighted line are also shown together with horizontal lines showing the average values of the electron densities obtained for the component phases using ten different particles, data from Table 5[link]. (c) Segmented volumes of the region shown in panel (a). Colour codes: red, air porosity; light blue, water porosity; yellow, C-S-H gel (and AFt); light green, CH; light pink, FA; and brown, C2S.
