Flash-calcined dredging sediment blended cements: effect ...

The hydration kinetics of the CFC blended cements were studied by isothermal calorimetry. The calorimetry heat flow results are shown in Fig. 2.It is observed that the higher the cement replacement is, the higher the heat flow during both the induction and the main hydration period become (when normalised to cement content).

On the initial stages of cement hydration | SpringerLink

After the initial mixing of cement, an induction period occurs during which its consistency remains constant. Thickening occurs at the end of this period when the consistency is observed to increase very rapidly. In this paper we propose a reaction-diffusion model for the hydration of tricalcium ...
