PROBLEM TO BE SOLVED: To provide a refractory mortar for refractory brick in a molten metal vessel or a secondary refining furnace, having enhanced water resistance, safety and storage property and enhanced adhesiveness with a refractory brick.SOLUTION: There is provided a refractory mortar can exhibit excellent water resistance by presence of a film membrane even when exposed to steam in a drying process after processing by blending re-emulsified shape powder resin of 1.5 to 5 mass% by outer percentage based on 100 mass% of a refractory powder, re-emulsifying the re-emulsified shape powder resin by a processing water during processing the refractory mortar (manufacturing refractory brick), then generating the film membrane surrounding the refractory powder by drying, can secure safety without needs for use of a deleterious substance as a self-curing mortar, can enhance storage property without cure by a chemical reaction as the self-curing mortar and can enhance adhesiveness with the refractory brick during utilization after drying because clay adds adhesiveness during the utilization after drying.SELECTED DRAWING: None
【課題】溶融金属容器又は２次精錬炉における、内張耐火物として用いる、耐火れんが用の耐火モルタルで、耐水性、安全性及び保管性を向上し、耐火物れんがとの接着性も向上させた耐火モルタルの提供。【解決手段】耐火粉末１００質量％に対して外がけで１．５〜５質量％の再乳化形粉末樹脂を配合し、再乳化形粉末樹脂が耐火モルタルの施工時（耐火れんがの築造時）に施工水により再乳化した後、乾燥により耐火粉末を取り囲むようにフィルム膜を生成し、施工後の乾燥工程において水蒸気に曝されたとしても、このフィルム膜の存在により優れた耐水性を発揮でき、また、自硬性モルタルの様に劇物を使用する必要がなく、安全性を確保でき、自硬性モルタルの様に化学反応による硬化がなく、保管性が向上でき、乾燥後の稼働時においては粘土が接着性を付与するので、乾燥後の稼働時において耐火れんがとの接着性を向上できる耐火モルタル。【選択図】なし
