HYDRAULIC COMPOSITION FOR CENTRIFUGAL MOLDING
PROBLEM TO BE SOLVED: To provide a hydraulic composition, which provides a cured body of high strength by centrifugal molding and which also has excellent moldability.SOLUTION: The hydraulic composition for centrifugal molding comprises: a dispersant for hydraulic powder, comprising a polymer compound containing aromatic rings; one or more compound(s) selected from specific compounds having an oligoalkyleneoxy or polyalkyleneoxy group as an essential component and a sulfonic group, an alkyl group and/or a tertiary amino group at a terminal; hydraulic powder; a high strength admixture containing silica; an aggregate; and water. Thereby, the hydraulic composition is provided with a high yield value of the aromatic ring-based dispersant, resulting in a significant improvement in dispersibility and an improvement in slurry properties of the hydraulic composition itself.SELECTED DRAWING: None
【課題】遠心成型による硬化体が高強度で、且つ成型性にも優れた水硬性組成物の提供。【解決手段】芳香環を含む高分子化合物からなる水硬性粉体用分散剤と、オリゴアルキレンオキシ又はポリアルキレンオキシを必須とし、末端にスルフォン基、アルキル基及び／又は３級アミノ基を有する特定の化合物から選ばれる１種以上の化合物と、水硬性粉体と、シリカを含む高強度混和材と、骨材と、水とを含有することにより、芳香族環系分散剤の高い降伏値を付与し、分散性が大幅に改善され、水硬性組成物自体のスラリー性状が改善される遠心成形用水硬性組成物。【選択図】なし
