프리믹스 시멘트 종류 변화 및 CGS 치환에 따른 콘크리트의 물리적 특성
Physical Properties of Concrete According to Changing in The Types of Premix Cements and the Mixing Rate of CGS.
초록
In this study, Coal gasification slag(CGS) was replaced with fine aggregate to verify the physical properties of the concrete according to the change in cement types. As a result of the study, the use of CGS resulted in a decrease of superplasticizer and an decrease of AE agent. In addition, when 50% of mixed cement and CGS were replaced, the initial strength expression was delayed, and the strength enhancing effect was judged to be weak.
