An Experimental Study on appropriate water-binder ratio for development of ultra high strength concrete

초고강도 콘크리트 개발을 위한 적정 물-결합재비 선정에 관한 실험적 연구

In this study, we measured the relative density and the compressive strength in order to select the appropriate W/ B for the ultra-high strength concrete development. If W/B is lowered than the W/B of highest relative density, it was confirmed that the strength is lowered. However, if water is increased than the W/B of highest relative density, the relative density is decreased compressive strength was similar. The selection of the W/B of the lower than the highest relative density is not appropriate. Appropriate W/B is selected to be more than the maximum relative density of W/B.
