UNSHAPED REFRACTORY
PROBLEM TO BE SOLVED: To provide an unshaped refractory using not cement but colloidal silica as a binder for a refractory material, capable of reducing the problem of cure shrinkage and also reducing the generation of cracks in the body to be applied after curing.SOLUTION: Provided is an unshaped refractory comprising: a refractory material; colloidal silica; and a magnesium carbonate based raw material, in which the mass ratio of the magnesium carbonate based raw material to the mass of the silica solid content derived from the colloidal silica(the magnesium carbonate based raw material/the silica solid content) is 0.001 to 4.
【課題】耐火材料の結合剤としてセメントではなくコロイダルシリカを使用した不定形耐火物において、養生収縮の問題を低減し、かつ、養生後の施工体に亀裂が発生するのを低減すること。【解決手段】耐火材料と、コロイダルシリカと、炭酸マグネシウム質原料とを含有し、前記コロイダルシリカ由来のシリカ固形分の質量に対する前記炭酸マグネシウム質原料の質量比（炭酸マグネシウム質原料／シリカ固形分）が、０．００１以上４以下である不定形耐火物。【選択図】なし
