Visual observations of sample S100 surfaces. Samples were cured for 14 days (fog room, at 20 °C and 99% RH) and subsequently removed to laboratory conditions, at 20 °C and 55% RH. Arrows point to microcracks patterns, which are coloured in red. (The microcracks were most present on the top surface, while on the other sides of samples their appearance was less).
