Provided is an additive for a hydraulic composition, which is capable of suppressing changes in properties due to the amount of fine particle components or the like and obtaining constant properties (viscosity, fluidity and the like) even if an aggregate that is insufficient in quality and has a large variation in the content of fine particle components or the like such as clay is used, and which is also excellent even if the use amount of the additive is small. An additive for a hydraulic composition, which is characterized by containing a component A represented by general formula (1) and a component B represented by general formula (2). 本发明提供即使使用品质不充分、粘土质等微粒成分等的含量的偏差大的骨料，也能够抑制由微粒成分等的多少引起的性状的变化，得到恒定的性状(粘性、流动性等)，而且即使其使用量少也优良的水硬性组合物用添加剂。一种水硬性组合物用添加剂，特征在于，含有：由通式(1)表示的A成分、和由通式(2)表示的B成分。
