Low Cement Castables (LCC) containing Tabular Alumina provide solutions for challenging refractory applications with high temperature demands. Beside high-performance Calcium Aluminate Cements (CACs), the selection of alumina is a key component to achieve desired LCC properties. The choice of alumina influences various castable properties like water demand, flow behavior and strength development. This study investigates the influence of CAC,calcined- and reactive alumina on LCC properties wit...Low Cement Castables (LCC) containing Tabular Alumina provide solutions for challenging refractory applications with high temperature demands. Beside high-performance Calcium Aluminate Cements (CACs), the selection of alumina is a key component to achieve desired LCC properties. The choice of alumina influences various castable properties like water demand, flow behavior and strength development. This study investigates the influence of CAC,calcined- and reactive alumina on LCC properties within typical LCCs ranges. A white Calcium Aluminate Cement with ~64% Al2O3 and CA as the main reactive phase is chosen as a binder (HPC). Workability, hardening properties and cold crushing strength after firing at different temperatures are compared.» weiterlesen» einklappen
