Effect of Micro-Sized Alumina Powder on the Hydration
Micro-sized alumina powder is widely used in low cement high-alumina refractory castables. The hydration of calcium aluminate cement can be affected by adding micro-sized alumina powder. This work addresses the hydration of a commercial cement at 25°C with 50 wt micro-sized alumina powder added. The hydration heat was measured by isothermal micro-calorimetry.
Thermal shock and size effects in castable refractories
· Chemical reactions consisted of (1) the hydration of residual unreacted calcium aluminate cement to form additional cementitious phases (2) the leaching of CaO from the castable and its reaction to form CaCO/sub 3/ and calcium formate (3) the hydration of alumina to form boehmite and (4) the dissolution of SiO/sub 2/ by steam.
