Abstract: PROBLEM TO BE SOLVED: To provide a foaming agent for a hydraulic composition, particularly a foaming agent composition capable of obtaining a hydraulic composition having stable foam effective to reduce the weight of paste, slurry, mortar, concrete, or the like containing cement, plaster, or the like as a hydraulic material. SOLUTION: A foaming agent composition for a hydraulic composition comprising an anion surfactant and a cationic polymer is present when the hydraulic composition is produced. Stability of foam introduced into the hydraulic composition is remarkably improved. The foaming composition is particularly useful for various hydraulic compositions such as a light-weight hydraulic composition because it can stabilize foam while maintaining flowability of the hydraulic composition.
