Hydration of Calcium Aluminate Phases at Different Temperatures

Popis výsledku v původním jazyce

Mayenite (C12A7) and calcium dialuminate (CA2) are both components of Calcium aluminate Cement (CAC). The hydration of these phases depends on initial conditions especially on the temperature. Pure phases were synthesized by solid-state reaction. The hydration was carried out at three different temperatures – 20 C, 30 C and 60 C. The course of hydration was investigated by isothermal calorimetry. The results prove, that higher temperature increase reactivity of phases and decrease their initial period of hydration. The X-ray diffraction analysis (XRD) identified the hydration products of CA2 as katoite (C3AH6) and gibbsite (AH3). The hydration products of C12A7 depends on the temperature. At 20 C the major products are C2AH8 and CAH10. At 30 C CAH10 disappears and only C2AH8 remains. At 60 C the only stable hydrates – C3AH6 and AH3 are formed.
