METHOD FOR PRODUCING CEMENT-BASED SOLIDIFYING MATERIAL
PROBLEM TO BE SOLVED: To provide a method for producing a cement-based solidifying material, in which the cement-based solidifying material can be obtained, which material reduces the amount of the dust to be generated therefrom when sprayed, has excellent storage stability, and further expresses a satisfactory dust suppression effect to even fine powder-containing hydraulic powder even when a small amount of a chemical is added.SOLUTION: A method for producing a cement-based solidifying material comprises a step of mixing an aqueous solution with the hydraulic powder, which solution contains by a predetermined ratio at predetermined concentration: an ether compound (A) obtained by using tri- or higher hydric alcohol and 1-5C monohydric alcohol; glycerol (B); and one or more kinds of polyether (C) selected from an ethylene oxide-methanol adduct, the average addition molar number of whose ethylene oxide is 5-20, and polyethylene glycol having 200-1,200 weight-average molecular weight so that a ratio of the ether compound (A) to the hydraulic powder, another ratio of the glycerol (B) to the hydraulic powder, a different ratio of the polyether (C) to the hydraulic powder, and a separate ratio of the water to the hydraulic powder become predetermined values, respectively.SELECTED DRAWING: None
【課題】散布時等の粉塵発生量が少なく、貯蔵安定性が良好なセメント系固化材が得られ、更に、微粒子を含む水硬性粉体に対しても前記薬剤の添加量が少量でも十分な粉塵抑制効果が発現する、セメント系固化材の製造方法を提供する。【解決手段】３価以上の多価アルコールと炭素数１以上５以下の１価アルコールとのエーテル化合物（Ａ）と、グリセリン（Ｂ）と、エチレンオキサイド平均付加モル数が５以上２０以下であるメタノールのエチレンオキサイド付加物及び重量平均分子量２００以上１２００以下のポリエチレングリコールから選ばれる１種以上のポリエーテル（Ｃ）とを、所定の質量比、所定の濃度で含有する水溶液を、前記（Ａ）、（Ｂ）、（Ｃ）及び水が水硬性粉体に対して所定比率となるように、水硬性粉体と混合する工程を有するセメント系固化材の製造方法。【選択図】なし
