Figure 2. The complex 3D pore structure of GIC is visible in the reconstructed and binarised X-ray images.

Figure 2

Smaller pores are visible for the less viscous cement, Aqua (a). This is confirmed by the counts of pores (y axis) according to their volume (x axis), here plotted in a log-log scale. With ageing, a decrease in the count of smaller pores for Aqua is observed, thus indicating that the pore volume becomes smaller than the resolution of the instrument (c). Larger pores are visible in the more viscous cement, Poly (b). With ageing, an overall reduction in the pore size was also observed for the latter, although no significant changes in the small pore range can be noticed (d).
