Abstract1   본 연구는 물결합재비 40%인 일반강도 영역에서 FA, BS 및 FA+BS의 광물질 혼화재의 0~30%의 치환율 변화가 분체계 고유동 콘크리트의 재료분리 저항성 등 제반 특성에 미치는 영향에 대하여 분석하였다. 특히 고유동 콘크리트에서 밀도가 작은 분체의 치환율을 증가시킬 경우 액상 콘크리트의 점성저하로 재료분리가 증대될 수 있지 않은지, 또한 J-ring시험으로 철근 장애부에 의한 재료분리 정도에는 영향을 미치지 않을지 등 제반특성을 검토 분석하였다.
Abstract2   The aim of the research is to evaluate the influence of various replacing ratios of supplementary cementitious materials(SCMs) such as fly ash(FA), blast furnace slag(BS), and both FA and BS on general properties including segregation resistance as a powder based high fluidity concrete of normal strength grade with water-to-cement ratio 0.40. Specifically, by replacing the SCMs with low density powders, it was assessed that the decreased segregation resistance due to the decreased viscosity by J-ring test. As a result of the experiment, from the general test, the mixtures with SCMs showed increased segregation resistance by increased viscosity as the references, while some segregation was shown from J-ring test due to the decreased density of fresh state mixture related with the capacity of delivering coarse aggregate.
