Hydration of C3S in salt solutions having ions in common with its hydration products was investigated by calorimetry and aqueous phase analyses. Soluble calcium salts, which depress hydroxyl ion concentrations in solution by promoting Ca(OH) 2 precipitation, were observed to accelerate hydration. Ac

A kinetic model describing the hydration of C3S has been developed. The model is predicated on the assumption that the formation of a final hydrate phase initiates in transient hydrate layers which surround the anhydrous grains. This transformation results in the onset of the acceleratory period. T
The hydration of quartz-tricalcium silicate mixtures at 175ยฐC has been studied. The samples, precured at 25ยฐC for different periods of time, in the range 0 -16 hours, have been autoclaved for 8 hours. Upon addition of quartz to the system water-tricalcium silicate, some remarkable modifications have
