Zusammenfassung:	PURPOSE:To obtain the titled inexpensive castable having excellent cracking resistance, capable of reducing the amount required for execution, free from baking with a coating material, consisting essentially of SiO2 and Al2O3, by adjusting the ratio of SiO2 ultrafine powder/Al2O3 ultrafine powder into a specific range. CONSTITUTION:(A) A refractory aggregate such as chamotte or high-alumina raw material is blended with (B) refractory ultrafine powder obtained by mixing (a) spherical silica ultrafine powder having
