Selected slices of the PXCT tomograms for neat PC paste after five months of hydration at room temperature. (a) A horizontal slice of the electron-density dataset, (b) the corresponding slice of the absorption dataset, (c) a vertical slice of the electron-density dataset and (d) the corresponding slice of the absorption dataset. Some regions are identified as different component phases, based on the electron-density values, using the labelling system shown in Table 1[link]. The highlighted regions with the HD_C-S-H/portlandite (phases 3/4 in orange circles) pair and MgO/C4AF (phases 10/11 in blue squares) pair are discussed in the text.
