고성능 콘크리트의 특성에 미치는 배합요인의 영향(1) - 제1보: 아직 굳지않은 상태의 특성 ( An Effect of the Mixing Factor Influencing to the Properties of High-Performance Concrete )

The concrete with excellent flowability, self-placeability and segregation-resistibility at fresh state and high strength and durability at state is called high-performance concrete.But,fundamental study for these kinds of concrete is not enough in our country. Therefore,this study is designed for analyzing the prooperties of high-performance concrete with the parameter of water contents and S/A (sand/aggregate ratio). From experimental reults, when the mixing of high performance concrete to W/B 25-35%.water contents was good to 177-183kg/m3. And S/A showed good to 44-47%.
