MONOLITHIC REFRACTORY FOR DRY SPRAYING CONSTRUCTION
To achieve working serviceable life needed for adjustment of construction thickness of a spraying constructed body or the like, when a refractory material to which no cement is added as a binder (hereafter, called "cement-free") is used as a monolithic refractory for dry spraying construction.SOLUTION: There is provided a monolithic refractory for dry spraying construction by mixing a cement-free refractory material, and a silica sol having concentration of a silica solid component of 20 mass% to 50 mass% or a silica sol by diluting the silica sol with water. The refractory material contains a compound of Mg or Ca with particle diameter of 1 mm or less as a curing agent, and a metal sulfate or a metal halide salt as a coagulant.SELECTED DRAWING: None
【課題】結合剤（バインダー）としてセメントを添加しない（以下、セメントフリーと表記する）耐火材料を乾式吹付け施工用不定形耐火物として用いた場合において、吹付け施工体の施工厚みの調整等に必要な作業可使時間の確保を実現すること。【解決手段】セメントフリーの耐火材料と、シリカ固形分の濃度が20質量％〜50質量％のシリカゾル又はシリカゾルを水で希釈したシリカゾルを混合する乾式吹付け施工用不定形耐火物である。前記耐火材料は、硬化剤として粒径1mm以下のMg又はCaの化合物、凝集剤として金属硫酸塩又は金属ハロゲン化物塩を含有する。【選択図】なし
