COPOLYMER FOR CEMENT ADMIXTURE, METHOD FOR PREPARING THE SAME, AND CEMENT COMPOSITION CONTAINING THE SAME

摘要

The present invention relates to a polycarbonic acid-based copolymer for a cement admixture, the cement admixture using the copolymer, and a producing method thereof, and more specifically, to a polycarbonic acid-based copolymer for a concrete chemical admixture which improves initial water-reducing ability due to excellent dispersing ability when being mixed with cement paste, mortar, concrete, and the like by giving stereospecificity inside the copolymer, maintains proper workability due to a low slump loss by preventing flowability degradation, and has high strength; to a cement admixture using the copolymer; and to a producing method thereof.
