A Study on the Characteristics of Cement, Concrete from kinds of Admixture for Rapid Hardening

조기강도 발현을 위한 혼화제별 시멘트 콘크리트의 특성 연구

The use of admixture(PNS type & PC type) played a important role in the development of rapid hardening concrete. This paper presents an experimental study on the effect of a kinds of admixture on hydration characteristics, mini slump, apparent viscosity of fresh cement pastes and workability, compressive strength properties of hardened concrete for rapid hardening. Measurements have showed that their characteristics depends on the type of the admixture. As a result, the excellent quality was obtained, also being widely used for the construction field is expected.
