DISPERSANT FOR HYDRAULIC COMPOSITION
To provide a polycarboxylic acid based dispersant for a hydraulic composition, even when clay-containing aggregate is used, capable of imparting excellent fluidity to a hydraulic composition.SOLUTION: A composition for a clay-containing dispersant for a hydraulic composition comprises: a component (A); a component (B); and a component (C) made of mutually different specified copolymers, in which the total ratio of the content of the component (B) and the content of the component (C) to the total of the content of the component (A), the content of the component (B), and the content of the component (C) is 5 to 20 mass%.SELECTED DRAWING: None
【課題】粘土を含む骨材を用いた場合でも、水硬性組成物に優れた流動性を付与できる、ポリカルボン酸系の水硬性組成物用分散剤を提供する。【解決手段】相互に異なる特定の共重合体からなる(A)成分、(B)成分、(C)成分を含有する、粘土含有水硬性組成物用分散剤であって、(A)成分の含有量と(B)成分の含有量の(C)成分の含有量の合計に対する、(B)成分の含有量と(C)成分の含有量の合計の割合が、5質量%以上20質量%以下である、粘土含有水硬性組成物用分散剤。【選択図】なし
