Fig. 8: Hydration study as a function of time and cement particle sizes.
a 2D views of the segmented anhydrous cement particles as a function of time. PXCT data shows that C4AF hydrates little up to 93 h. This is likely due to the low w/c ratio in the scanned volume and its slow hydration rate. b Volumes and cumulative volumes for the anhydrous cement particles as a function of the particle size, represented in logarithmic scale for easy comparison with Fig. 1. The particle sizes are computed as the mean Feret diameter frequency which measures object size along directions. The particles are represented grouped in sets of 2.5 microns, i.e. 0-2.5, 2.5-5.0 μm, etc. The maximum and Dv,50 values for the Lab-μCT and Syn-μCT are given in the panels. These data are scattered for PXCT because the limited height of the studied cylinder yields a poor representative elementary volume for this feature.
