PROBLEM TO BE SOLVED: To improve executability and strength without causing abnormality to fluidity in execution by adding a ceramic fiber to which a specific slight amount of additive is attached to a refractory heat-insulating castable. SOLUTION: A spraying solution obtained by dispersing or dissolving a minute amount of addition such as an organic thickener or surfactant into a solvent such as water, an alcohol, acetone, xylene, toluene or benzene is sprayed to ceramic fiber. The treated ceramic fiber in an amount of 3-50wt.% is added to a refractory heat-insulating castable. |
