Admixture for hydraulic composition and hydraulic composition
The invention relates to an admixture for a hydraulic composition and the hydraulic composition. Provided is an additive for a hydraulic composition, which is capable of exhibiting both excellent initial dispersibility and excellent flow retention in a hydraulic composition when used in the hydraulic composition. An additive for a hydraulic composition, which is characterized by containing a water-soluble vinyl copolymer that contains, in the molecule, a structural unit (1) comprising a compound represented by general formula (1), a structural unit (2) comprising a compound represented by general formula (2), and a structural unit (3) comprising a compound represented by general formula (3). When the total of the constitutional proportions of the constitutional unit 1, the constitutional unit 2, and the constitutional unit 3 is taken as 100 mass%, the constitutional unit 1 is contained in a proportion of 65-95 mass%, the constitutional unit 2 is contained in a proportion of 2-30 mass%, and the constitutional unit 3 is contained in a proportion of 0.1-25 mass%.
本发明涉及水硬性组合物用外加剂和水硬性组合物。本发明提供一种水硬性组合物用外加剂，通过将其用在水硬性组合物中，能够在水硬性组合物中发挥优异的初期分散性和优异的流动保持性这两者。一种水硬性组合物用外加剂，其特征在于，含有水溶性乙烯基共聚物，其在分子中包含由通式(1)表示的化合物形成的结构单元1、由通式(2)表示的化合物形成的结构单元2、以及由通式(3)表示的化合物形成的结构单元3，将结构单元1、结构单元2和结构单元3的构成比例的合计设为100质量％时，以65～95质量％的比例包含结构单元1，以2～30质量％的比例包含结构单元2，且以0.1～25质量％的比例包含结构单元3。
