A tap hole mix for a blast furnace and the like containing essentially no binder comprising either water or one or more of tar, pitch and asphalt with or without the addition of a resin, which comprises refractory materials composed of grains of one or more of clay, chamotte, alumina, silicon carbide and the like and a carbonaceous material, a hardener comprising a novolak-type phenol resin to which a substance which produces formaldehyde by the thermal decomposition or a thermosetting resin is added in a definite proportion, and an alcoholic solvent. The present inventive tap hole mix is rapidly hardened or set, has excellent corrosion resistance and does not cause the occurence of unpleasant smoke and abnormal dusts.
