DISPERSANT FOR COMPOSITION THAT CONTAINS POZZOLANIC REACTIVE SUBSTANCE OR LATENT HYDROTROPIC SUBSTANCE
To provide a technique for improving flowability of a composition that contains a pozzolanic reactive substance or a latent hydraulic substance.SOLUTION: A dispersant for compositions that contains a pozzolanic reactive substance or a latent hydraulic substance is provided, the dispersant comprising a polycarboxylic acid-based copolymer containing a structural unit (I) derived from an unsaturated dicarboxylic acid monomer in a ratio of 21.0 mass% or more. More preferably, the composition comprises the pozzolanic reactive substance or the latent hydraulic substance at a ratio of 41.0 mass% or more of the total solids content. More preferably, the polycarboxylic acid-based copolymer comprises a structural unit (II) derived from an unsaturated monocarboxylic acid-based monomer.SELECTED DRAWING: None
【課題】ポゾラン反応性物質または潜在水硬性物質を含む組成物の流動性を向上する技術を提供すること。【解決手段】不飽和ジカルボン酸系単量体由来の構造単位（Ｉ）を２１．０質量％以上の割合で含むポリカルボン酸系共重合体を含むものである、ポゾラン反応性物質または潜在水硬性物質を含む組成物用の分散剤を提供する。前記組成物は固形分の総質量に対してポゾラン反応性物質または潜在水硬性物質を４１．０質量％以上の割合で含むものであることがより望ましい。また当該ポリカルボン酸系共重合体は、不飽和モノカルボン酸系単量体由来の構造単位（ＩＩ）を更に含むことがより望ましい。【選択図】なし
