To provide a castable refractory which ensures curing strength and hardly causes trouble such as falling off at the time of removing, has small temperature dependence, can easily adjust the addition amount of a curing agent and a curing modifier, and hardly causes agglomeration and hardening failure during kneading in air temperature.SOLUTION: A castable refractory includes a refractory raw material, a binder, and a curing agent. The binder includes colloidal silica. The curing agent contains crystalline layered sodium silicate and does not contain magnesia having a particle size of 0.10 mm or less.SELECTED DRAWING: None
【課題】 養生強度を確保して脱枠時の脱落等のトラブルが起こりにくいとともに、温度依存性が小さく、硬化剤や硬化調整剤の添加量の調整が容易で、気温による混練中の凝集や硬化不良が起こりにくいキャスタブル耐火物を提供すること。【解決手段】 キャスタブル耐火物は、耐火原料と、結合剤と、硬化剤とを含み、結合剤はコロイダルシリカを含み、硬化剤は結晶性層状珪酸ナトリウムを含み、かつ、粒径０．１０ｍｍ以下のマグネシアを含まない。【選択図】 なし
