COPOLYMER FOR CEMENT ADMIXTURE, METHOD FOR PREPARING THE SAME, AND CEMENT COMPOSITION CONTAINING THE SAME
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.
본 발명은 시멘트 혼화제용 폴리카르본산계 공중합체, 그 공중합체를 이용한 시멘트 혼화제, 및 이의 제조방법에 관한 것으로 공중합체 내에 입체특이성을 주어 시멘트 페이스트, 모르타르, 콘크리트 등과 함께 혼합될 경우 분산성이 우수하여 초기 감수 성능을 향상시키고, 유동성 저하를 방지하여 슬럼프 로스가 적어 양호한 작업성을 유지하며, 높은 강도를 가지는 콘크리트 화학 혼화제용 폴리카르본산계 공중합체, 그 공중합체를 이용한 시멘트 혼화제, 및 이의 제조방법에 관한 것이다.
