Crushed stone powder is produced at the time of manufacturing of crushed stone and crushed sand. It is very important to make efficient use of this crushed stone powder. The purpose of this study is to investigate the properties（fluidity, filling, compressive strength, freeze-thaw resistance, etc.）of high fluidity and high strength regulated set cement concrete mixed two kind of crushed stone powder with different particle size together. As the results, it was recognized that fluidity and filling of concrete are affected by blend ratio of two kind of crushed stone powder and additional quantity of crushed stone powder. Furthermore, it became clear that the properties of high fluidity and high strength regulated set cement concrete mixed two kind of crushed stone powder are similar to the properties of that concrete mixed fly ash.
