EXTRUSION MOLDING HYDRAULIC COMPOSITION
To provide an extrusion molding hydraulic composition having excellent workability during extrusion molding even when porous low quality fly ash having much unburnt carbon is used.SOLUTION: There is provided an extrusion molding hydraulic composition which comprises the following component (A), cement, fly ash having a BET specific surface area of 0.5 m3/g or more and less than 12.0 m3/g and an ignition loss of 1% or more and 10% or less, and water. Component (A): a copolymer comprising a monomer (1a) represented by the general formula (1a) and a monomer (2a) represented by the general formula (2a) as constituent monomers, in which the ratio of monomer (2a) in the total constituent monomers is 15 mass% or more and 35 mass% or less and the weight average molecular weight is 40000 or more and 80000 or less.SELECTED DRAWING: None
【課題】未燃カーボンが多く、多孔質である低品質なフライアッシュを使用した場合においても、押出成形する際の作業性に優れる、押出成形水硬性組成物を提供する。【解決手段】下記（Ａ）成分、セメント、ＢＥＴ比表面積が０．５ｍ３／ｇ以上１２．０ｍ３／ｇ未満、且つ強熱減量が１％以上１０％以下であるフライアッシュ、及び水を含有する、押出成形水硬性組成物。（Ａ）成分：一般式（１ａ）で示される単量体（１ａ）と、一般式（２ａ）で示される単量体（２ａ）とを構成単量体として含み、全構成単量体中の単量体（２ａ）の割合が、１５質量％以上３５質量％以下であり、重量平均分子量が４００００以上８００００以下である、共重合体【選択図】なし
