Hydration of hydratable alumina in the presence of various forms of MgO

Ceramics International, 2006
Abstract This work investigates hydration behavior of hydratable alumina in the presence of several forms of magnesia used for production of refractory castables. The mixtures of hydratable alumina with reactive magnesia, fused magnesite and deadburnt magnesite were hydrated at 20 °C and 110 °C.

Drying behavior of hydratable alumina-bonded refractory castables

Journal of the European Ceramic Society, 2004
Abstract The drying behavior of a hydratable alumina-bonded (HAB) refractory castable was evaluated by thermogravimetric tests and compared with an ultra-low cement composition (CAC). The key properties of monolithic refractory dry-out performance, such as fluid permeability and mechanical strength, were also determined.

Hydration of sodium phosphate-modified high alumina cement

Journal of Materials Research, 1994
High strength can be achieved in high alumina cement (HAC) through the incorporation of phosphate-based additions at levels of 10 and 20 wt. %. In order to establish the mechanism that results in higher strength, the effects of a variety of condensed sodium phosphates (NaPO3)n, (NaPO3)n · Na2O, Na5P3O10, and (NaPO3)3 were studied.
