PROCESSING OF ZIRCONIA AND CALCIUM ALUMINATE CEMENT

mixtures of pure zirconia (m-ZrO 2) and calcium aluminate cement (HAC). Two commercial powders of pure zirconia were employed as reactants. One of these powders had a coarse mean particle size (d 50 = 8 μm) and the other was a submicrometer sized power (d 50 = 0.44 μm). Several compositions containing different proportions of HAC (5 to 30 mol. % CaO in ZrO 2) …

HYDRATION OF CALCIUM ALUMINATE CEMENT PHASES CA …

tivity of calcium aluminate phases increases with the calcium content of the phase, and therefore CA shows higher reactivity than CA 2. Some literature even claims that CA 2 would be an almost inert phase with regard to hydraulic reactivity. This study investigates the hydration of pure CA and blends of CA and CA 2 using heat flow calorimetry and quantitative in-situ X-ray …
