The Experimental Study on the Influence of Relation between Cement Paste and Aggregate Volume to Effect the High Folwing and Engineering Properties of High Flowing Concrete

고유동콘크리트의 유동특성 및 공학적 특성에 미치는 시멘트페이스트용적 및 골재용적과의 관계에 관한 실험적 연구

High flowing concrete has been made using a combination of much amount cementitious materials and addition of SP agents, so that it makes possible to high flowing properties of fresh concrete. In the fluid mechanical and rheological point of view, high flowing concrete is affected on the relation between cement paste and aggregate of volume. In this experimental study, it is measured high flowing concrete of slump-flow about 65$\pm$5cm according to 0.54~0.80 of volume ratio and to analysed the properties of high flowing concrete in fresh and hardened concrete. It is the aim of this study to consider the affection of high flowing properties accoring to cement paste to aggregate ratio of volume on the combination of concrete.
