Hydration of calcium aluminates at 60°C – Development paths of C₂AH_x in dependence on the content of free water

The influence of water loss during the hydration of calcium aluminates on the phase development is investigated at 60°C. This is relevant for applications in which calcium aluminate cement ( CAC ) based formulations are exposed to quick drying during hydration. The presented results provide new insights into the well‐known conversion processes occurring in CAC pastes. Using in situ XRD two different routes of the development of initially formed...
