CSA의 장점은 무엇인가? | 칼슘설포알루미네이트(Calcium SulfoAluminate; 이하 CSA) 는 팽창제로써 OPC와 혼합하여 다양하게 사용되어온 재료이다.CSA는 풍부한 Ca를 포함하고 있어 수화반응시 ettringite를 형성하여 조직을 치밀하게 하고 내부 공극을 감소시켜 강도와 내구성을 향상시킨다. 특히 기존의 OPC와 여러 혼화재료를 혼합한 결합재에 CSA를 일부 치환하여 건조수축 감소와 강도향상, 응결시간 단축 등의 효과를 얻을 수 있었다(Péra and Ambroise, 2004; Chaunsali and Mondal, 2016; Bernard et al. | |
고유동 콘크리트의 결합재는 무엇으로 혼합되어 있는가? | 고유동 콘크리트에 대한 연구는 주로 보통 포틀랜드 시멘트(Ordinary Portland Cement, 이하 OPC)를 기반으로 하는 결합재와 콘크리트에 관한 연구가 중심이다. 특히 결합재는 OPC, 고로슬래그 미분말(Ground Granulated Blast Furnace Slag, 이하 GGBFS), 플라이애시(Fly Ash, 이하 FA), 메타카올린(MetaKaoline, 이하 MK), 실리카 퓸(Silica Fume), 석회석 분말(Limestone powder) 등을 여러 비율로 혼합한 것을 사용한다. | |
고유동 콘크리트의 특성은 무엇인가? | 이러한 고품질의 건설 구조물을 시공하기 위한 많은 기술이 개발되고 있다. 고유동 콘크리트(High Fluidity Concrete, 이하 HFC)는 과밀철근과 복잡한 형상에 적용할 수 있는 높은 시공효율을 가지고 있어 기술의 개발과 구조물에 적용이 확대되고 있다(Choi et al., 2010). |
