The XRD analysis showed (Fig. 8) that during the hardening of
AAC samples, tobermorite and calcite formed and some sand remained
not reacted (as seen from the XRD patterns corresponding
to quartz).
It was established that the intensity of crystalline tobermorite
corresponding peaks in the AAC samples, which contain different
CF additive of 0.1%, is higher than that of AAC samples without
mentioned additive. On the other hand, the intensity of calcite
corresponding peaks in the AAC samples with different CF additive
is lower than that of AAC samples without CF additive.
