seem to occur at a faster rate at higher w/s ratios. At 80°C and a low gypsum
content, C AF hydrates to form the cubic phase. The conversion of

ettringite to the monosulfate also occurs at a faster rate. A combination of
higher w/s ratios and high temperatures is conducive to faster hydration and
inter-conversion.
