NAITO HIROKI / SUGANUMA YUKI / FURUTA AKIHIRO / TANAKA YOSHIMASA

To provide an additive for hydraulic compositions, which is added to a hydraulic composition to reduce a change in flowability of the hydraulic composition over time regardless of the temperature of its use, and properly control the amount of air, while preventing an undue delay in the setting time of the hydraulic composition.SOLUTION: Provided is an additive for hydraulic compositions, comprising a specific component A, a specific component B, and at least one selected from a specific component C and a specific component D.SELECTED DRAWING: None

【課題】水硬性組成物に添加することで、使用温度に関わらず、水硬性組成物における経時による流動性の変化が少なく空気量の調整が適宜可能であり、一方で、水硬性組成物の凝結時間を過度に遅延させない水硬性組成物用添加剤を提供する。【解決手段】所定のＡ成分と、所定のＢ成分と、所定のＣ成分及び所定のＤ成分から選択される少なくとも１つと、を含有することを特徴とする水硬性組成物用添加剤。【選択図】なし
