Abstract
An insulating monolithic refractory material having sufficient curing strength and usable time ensured and exhibiting excellent stability at high temperature. The insulating monolithic refractory material comprises a binder and a refractory raw material; a bulk specific gravity thereof is 0.8 to 1.8 when a kneaded mixture of the insulating monolithic refractory material with water is cured at normal temperature for 24 hours and then dried at 110° C. for 24 hours; the binder comprises a calcium aluminate cement including CaO and Al2O3 as chemical components and a strontium aluminate cement including SrO and Al2O3 as chemical components; and on the basis of 100% by mass as a total mass of the binder and the refractory raw material, a content of the strontium aluminate cement is 2 to 10% by mass, and a content of CaO derived from the calcium aluminate cement is 1 to 12% by mass.
