✦ Synopsis

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. The model predicts C-S-H formation to be controlled by interfacial processes during the acceleratory period and by diffuslonal processes thereafter and that the growth of particles is essentially one-dimensional throughout the course of both the acceleratory and post-acceleratory periods.

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
