Abstract
The present invention provids an admixture composition for hydraulic material that is capable of enabling minute air to be entrained into a hydraulic material composition and imparting an excellent the freeze/thaw durability to the hydraulic material. The object of the present invention is accomplished by an admixture composition for hydraulic material which contains component (A) and component (B) as essential components. The component (A) is a polyoxyalkylene polymer possessing a side chain containing a carboxyl group and the component (B) is a compound which is represented by the general formula (B-1) or (B-2).
