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

β¦ Synopsis
Based on conceptual models for the stages in the hydration of trlcalcium silicate, a mathematical model was developed. The separate resistances in the mathematical model correspond to the phenomenological stages of the conceptual model. Comparison of model output with available hydration data gave a reasonable fit between the model and the data.

On obtlent un accord ralsonnable entre le modele et les donnees experimentales du degre d'hydratatlono

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.
Although the chemistry of cement has been under study for over 100 years, its mechanism of hydration is not yet fully understood. Various authors (i-3) have recently tried to come to grips with this basic problem, each summarizing the available data on the hydration of portland cement/tricalcium si
