ADDITIVE FOR CONCRETE COMPOSITION, AND CONCRETE COMPOSITION
To provide an additive for a concrete composition, in which an additive solution has high stability and which imparts excellent material separation resistance to a concrete composition and the like having high followability, wherein a concrete-hardened body and the like obtained therefrom can show excellent freeze-thaw resistance.SOLUTION: An additive for a concrete composition comprises a carboxylic acid-based copolymer and/or its salt, a water-soluble cellulose ether, gums, an antifoaming agent, and an organic amine salt of an aliphatic alcoholic phosphate, wherein ionic strength derived from the carboxylic acid-based copolymer is 0.02 to 0.8.SELECTED DRAWING: None
【課題】混和剤溶液の安定性が高いとともに、流動性の高いコンクリート組成物等に対して、優れた材料分離抵抗性を付与し、更に、得られるコンクリート硬化体等が良好な凍結融解抵抗性を示すことができる。【解決手段】カルボン酸系共重合体及び／又はその塩と、水溶性セルロースエーテルと、ガム類と、消泡剤と、脂肪族アルコールリン酸エステルの有機アミン塩とを含有し、カルボン酸系共重合体に由来するイオン強度が０．０２〜０．８であるコンクリート組成物用混和剤。【選択図】なし
