Distribution of the phases after (top row) 24 h and (bottom row) 30 h of cement hydration. From left to right, the distribution maps integrate the contribution of all the identified phases and the amorphous, C-S-H, ettringite, mullite, portlandite and alite phases. Red values indicate a higher content of the phase in the distribution map. Black values indicate voids (Total map) and voids or absence of phase (all other maps). Because all the maps were constructed from the number of counts integrated according to the procedure described in the Materials and methods section, they were scaled individually, and the sum of the colours of each map for the individual phases does not equal the colour of the total intensity map. The white circle of 1.3 mm diameter corresponds to the limit of the sample.
