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%.
