Formation of chloroaluminates in calcium aluminate cements
· The formation of hexagonal chloroaluminates in mortar specimens pre-cured at 20 40 and 60°C for two weeks and stored in a 0.5 M NaCl solution for up to 255 days has been studied. The appearance of this phase as a function of time has been monitored by X-ray diffraction. In addition its microstructure has been observed by means of backscattering electron microscopy.

Calcium aluminate cements (CACs) represent an interesting alternative because their pore water pH ranging from 11.4 to 12.5 is reduced as compared to OPC (Goñi et al. 1991 ). The main difference between Portland and calcium aluminate cements lies in the nature of the active phase that leads to setting and hardening.
