nate hydrate were identified by their characteristic peaks at about 80 ± 5°,
115 ± 15°, 200°, 160 ± 20°, 470 ± 10°, and 300°C respectively.
A high early strength calcium sulfoaluminate cement can be
formed from the raw materials slag, clay, fly ash, silica, etc. [86] Hydration

of the system C A S-CS-C AF was carried out by DTA to investigate the

rate of conversion of ettringite (high calcium sulfoaluminate phase) to the
monosulfoaluminate phase.
