The present invention is a dispersant composition for a hydraulic composition, the dispersant composition containing a polymer (A) which has carboxylic acid group-containing monomer units and a sugar compound (B) which has a molecular weight of 1,000 or less, and the pH of the dispersant composition at 22°C being 7.5 or lower. L'invention concerne une composition d'agent de dispersion pour composition hydraulique qui comprend un polymère (A) possédant une unité monomère ayant un groupe acide carboxylique, et un glycoconjugué (B) de masse moléculaire inférieure ou égale à 1000, et qui présente un pH à 22°C inférieur ou égal à 7,5. 本発明は、カルボン酸基を有するモノマー単位を有する重合物（Ａ）、及び分子量が１，０００以下の糖化合物（Ｂ）を含有し、２２℃でのｐＨが７．５以下である、水硬性組成物用分散剤組成物である。
