✦ Synopsis

Based on a generally accepted conceptual model for the hydration of tricalcium aluminate, a mathematical model was developed for the kinetics of hydration. The model was solved, illustrated, and compared to experimental heat release data. Results suggested that pore diffusion through a hexagonal phase barrier layer, dissolution of this layer and crystallization of the cubic phase from solution were all contributing resistances in the model, although pore diffusion through the barrier layer was the ratecontrolling step.

The effect of glucose and some glucose oxidation products on tricalcium aluminate hydration has been studied. The results are in agreement with the theory that stabilization of hexagonal C,AH13 determines the retardation. It is assumed that the glucose oxidation products are more effective retarders
