Abstract

The present invention relates to a composition for forming concrete and concrete manufactured therefrom. More specifically, the present invention relates to a composition for forming concrete containing an admixture and concrete manufactured therefrom. In order to solve the problems of condensation delay and initial strength deterioration of the concrete caused by a retarder in the case of conventional concrete used in extreme hot environment, a repeating unit comprising phosphate is introduced into the admixture so that the slump maintenance performance is maximized without using the retardant, initial dispersing force deterioration is prevented, and excellent workability is provided.

콘크리트 형성용 조성물 및 이로부터 제조된 콘크리트에 관한 것이다. 보다 구체적으로, 종래 극서 환경에서 사용되는 콘크리트의 경우에 지연제로 인해 발생하는 콘크리트의 응결 지연 및 초기 강도저하 문제를 해결하기 위해, 포스페이트를 포함한 반복 단위를 혼화제에 도입함으로써, 지연제를 쓰지 않더라도 콘크리트의 슬럼프 유지 성능을 극대화하고, 초기 분산력 저하를 막으며, 우수한 작업성을 부여하는 혼화제를 포함한 콘크리트 형성용 조성물 및 이로부터 제조된 콘크리트에 관한 것이다.
