Table 6. Volume percentages for the cement pastes at five months of hydration renormalized after excluding air porosity determined by tomographic segmentation.
The corresponding values for t = 0 are given to highlight the evolution of the hydrates. The t = 0 values were obtained from the Rietveld quantitative phase analysis for the anhydrous cements and they were renormalized taking into account the added water.
