MONOLITHIC REFRACTORY FOR DRY SPRAYING AND DRY SPRAYING CONSTRUCTION METHOD USING THE SAME
To provide a monolithic refractory for dry spraying having excellent versatility which, when used in a dry spraying construction method, can increase the curing strength of an obtained construction body, can maintain the shape of the construction body even in an application to which an impact or an external force, which has been difficult to use in a conventional product, is applied.SOLUTION: A monolithic refractory for dry spraying is used in a state of containing dry powder of a refractory material, dry powder of alumina cement, and a silica sol having a silica solid concentration of 20-50%. The monolithic refractory for dry spraying includes the alumina cement in a range of 1-5% in outer percentage with respect to 100% of the refractory material, the silica sol in which a silica solid content contained in the silica sol is in a range of 3-30% in outer percentage with respect to 100% of the refractory material, and dry powder of hydraulic alumina in the range of 0.7-2.0% in outer percentage with respect to 100% of the refractory material. The construction method using the monolithic refractory is also provided.SELECTED DRAWING: None
【課題】乾式吹き付け施工方法に用いた場合に、得られる施工体の養生強度を高めることを実現し、従来製品では使用が難しかった衝撃や外力がかかる用途においても施工体形状を維持することができる、汎用性に優れた乾式吹き付け用不定形耐火物の提供。【解決手段】乾粉の耐火材料と、乾粉のアルミナセメントと、シリカ固形分の濃度が２０％～５０％のシリカゾルとを含む状態で使用される乾式吹き付け用不定形耐火物であって、アルミナセメントを、前記耐火材料１００％に対して外掛けで１％～５％の範囲内で含み、シリカゾルを、そのシリカゾル中に含まれるシリカ固形分が、前記耐火材料１００％に対して外掛けで３％～３０％となる範囲内で含み、さらに、乾粉の水硬性アルミナを、前記耐火材料１００％に対して外掛けで０．７％～２．０％の範囲内で含む乾式吹き付け用不定形耐火物及び該不定形耐火物を用いる施工方法。【選択図】 なし
