Abstract Hydratable alumina (HA) is a superior Ca-free refractory binder, but the quick hydration rate restricts the working time of castables bonded with HA. In this work, HA was grounded for 1 h and 6 h by a rotational ball mill to study the effect of grinding on the hydration of HA and properties of HA-bonded castables. HA samples with and without

Abstract The results of infrared measurements on hydrated Na β″-alumina indicate that water molecules occupy mid-oxygen and vacant Na+ ion sites in the conduction layers. At H2O contents of about 0.2 molecules per formula unit, the ration of the number of molecules on the mid-oxygen and vacant sites at 25°C is close to the ratio of the numbers of the

Hydration of lithium β-alumina
The Journal of Chemical Physics, 1982The hydration reaction of Li β-alumina has been studied using infrared measurements of large single crystals equilibrated at controlled water vapor pressure (2–80 kPa) and temperature (250–450 °C) conditions. The equilibrium H2O concentrations in the conduction plane can be carried continuously and reversibly up to a saturation limit of about 1.8 H2O ...

Thermal Decomposition of Hydrated Alumina Cement (CAH10)
Cement and Concrete Research, 1998It is known that the initial product of hydration of high-alumina cement at low temperatures, often labeled “CAH 10,” contains both crystalline and amorphous portions. The thermal decomposition of this product was studied in several samples. This study was carried out by two different methods: derivative thermogravimetric analysis (DTG) and x-ray ...

Mechanisms of Reaction of Hydratable Aluminas
Journal of the American Ceramic Society, 1999The reactivities of four hydratable aluminas were investigated. Rates of heat liberation during hydration from 15° to 55°C were determined by isothermal calorimetry. Rates of heat evolution show two peaks. An initial mixing peak is due to wetting and initial dissolution reactions.
