摘要
The present work involves using differential scanning calorimetry (DSC) in an investigation of the thermal behaviour of hydration products in ground granulated blast-furnace slag (ggbs). The two-step loss of water from calcium silicate hydrates and dehydroxylation of calcium hydroxide (Ca(OH)(2)) contribute, respectively, to the two major peaks in the DSC curves. Peaks due to the formation of ettringite and Fe2O3 solid solution were also found. The crystallisation peaks from amorphous phases in the ggbs are also significant in the DSC thermograms.
