ADMIXTURE FOR HYDRAULIC COMPOSITION AND HYDRAULIC COMPOSITION
To provide an admixture for a hydraulic composition whose performance is hardly deteriorated even if stored for a long period of time, and to provide a hydraulic composition containing the admixture.SOLUTION: An admixture for a hydraulic composition of the present invention contains components A, B, and C: the component A, which is water having a redox potential of 0 mV or more at 25°C; the component B, which is a dispersant containing at least one selected from a polycarboxylic acid-based dispersant comprising a predetermined constitution unit and a lignin sulfonic acid-based dispersant; and the component C, which is a preservative component.SELECTED DRAWING: None
【課題】長期間保管してもその性能が劣化し難い水硬性組成物用混和剤及びそれを含有した水硬性組成物を提供する。【解決手段】２５℃における酸化還元電位が０ｍＶ以上の水であるＡ成分と、所定の構成単位を含むポリカルボン酸系分散剤およびリグニンスルホン酸系分散剤から選ばれる少なくとも１つを含む分散剤であるＢ成分と、防腐成分であるＣ成分と、を含有することを特徴とする水硬性組成物用混和剤およびそれを含有する水硬性組成物。【選択図】なし
