摘要： PROBLEM TO BE SOLVED: To prevent the explosive fracture of a monolithic refractory due to drying by using a conjugated fiber which is constituted on the basis of the mechanism of the explosive fracture of the monolithic refractory. SOLUTION: The explosive fracture of the monolithic refractory due to drying can be prevented by that the monolithic refractory includes the conjugated fiber where a first ingredient 1 consisting of polypropylene is compounded with a second ingredient 2 consisting of an organic substance whose melting point is lower than that of polypropylene. In this case, when the cross section of the composite fiber is a side-by-side type or an eccentric core-sheath type, voids formed respectively at the melting of the first ingredient 1 and the second ingredient 2 can assure a large void width each comparing with a sheath core type having a same cross sectional area.
