The duration of the induction period in the hydration of C3S can be altered by several means. Fast cooling after burning, fine grinding and an excess of water shorten the induction period. The induction period gets prolonged by slow cooling of the sample, by long lasting storage and by doping with A
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 mutual interaction of tricalcium silicate (CRS) and B-dicalcium silicate (B-CpS) in their combined h~dration was studied. The rate of B-CpS hydration was accelerated significantly in the presenc~ of CRS. The rate of CRS hydration was retarded, but only i~ the presence of~large amounts of B-C2S.
