Beschreibung
Zusammenfassung:	PURPOSE: To obtain an admixture containing the emulsion of a copolymer having specific free carboxyl groups in the polymer chain and capable of giving a concrete excellent in flowability, chargeability and separation resistance at a low cost. CONSTITUTION: The admixture for the highly flowable concrete contains the emulsion of a copolymer having free carboxyl groups obtained from a monomer component preferably in an amount of 3-60wt.% based on the whole amount of the polymer (e.g. a copolymer obtained from methacrylic acid, ethyl acrylate and triallyl cyanurate) in the polymeric chain. The concentration of the copolymer in its emulsion is preferably approximately 5-60wt.%. The content of an emulsifier (e.g. sodium polyoxyethylenealkyl ethersulfate) is preferably approximately 1-5wt.%.
