Cement Hydration - an overview | ScienceDirect Topics

In the first few hours of the test, the pozzolanic materials raised the heat of hydration as a result of the filler effect (Taylor, 1997), which favours hydration and pozzolanicity tween 5 and 12 hours, however, the reactions were highly exothermal and the upward slope on the curves was very steep, with the base cement exhibiting greater heat of hydration than the blended materials.
