초고강도 콘크리트의 특성에 미치는 물결합재비 및 부순모래 치환율의 영향에 관한 실험적 연구

In this study, it comes in today the ultra-high rising building while doing it was necessary to that place to ultra-high strength concrete engineering property there is a place where it proves. most it becomes of economical efficiency and using in actuality for a new method of water-binder 23.5, '2:7.5, 31.5% with replacement ratio of crushed sand 0, 20, 40% basic physical nature with background strength property and flow property it does analyze.As a result of flow property of ultra high strength concrete is good charging characteristic and with the fact that use of the crushed sand which it will be magnified.
