– up to 110 C (the main maximum on DTG curve at
about 80 C)—dehydration of AH3xH2O gel,
– 110–210 C (maximums on DTG for reference sample
at about 125 and 200 C)—overlapping effect of
dehydration of CAH10 and C2AH8 phases,
– 210–270 C (DTG maximum at about 240 C)—
decomposition of AH3 (gibbsite),
– 270–350 C—dehydration of C3AH6 (very small
effect), alternatively C3AS3-xH2x,
– above 700 C—decomposition of carbonates (not presented
in the figures).
