The hydration of calcium aluminates phases at low temperatures (5 °C, 10 °C, 15 °C)
Original language description
The paper is focused on the hydration of the calcium aluminate phases at low temperatures. Monocalcium aluminate (CA), monocalcium dialuminate (CA2), dodecacalcium heptaaluminte (C12A7) and tricalcium aluminate (C3A) were prepared by sintering stoichiometric ratios of CaCO3 and Al2O3 at high temperatures. The hydration was performed at three temperatures (5 °C, 10 °C and 15 °C) for 50 hours. The course of hydration was measured by isothermal calorimetry. The hydration products were characterized by X-ray diffraction (XRD) and combined differential thermal analysis - thermogravimetry (DTA-TG). The reactivity of phases decreased with higher content of alumina from C3A to CA2. The main hydration product of CA2 and CA was CAH10 at all temperatures. C3A and C12A7 created various hydration products, which depended on the temperature.
