(57) [Abstract] [PROBLEMS] To provide a hydraulic composition for concrete or the like, which has high fluidity and resistance to separation of aggregate, and can reduce surface bubbles. One having 6 to 30 carbon atoms in the molecule Polyhydric alcohol, having 6 to 30 carbon atoms in the molecule 1 Valenic mercaptans, alkylphenols having 6 to 30 carbon atoms in the molecule, amines having 6 to 30 carbon atoms in the molecule, or carboxylic acids having 6 to 30 carbon atoms in the molecule with alkylene oxides. A hydraulic composition comprising a water-soluble polymer composed of a polyalkylene oxide derivative added with 10 to 1000 mol, a high-performance water reducing agent, a defoaming agent, and a hydraulic powder. |
