The utilization of high flowing concrete in construction sites is a world wide trend, and it will be increase to need for high flowing concrete in our construction sites. While it is quite easy to make high-flowing concrete in the laboratory, controlling slump in the field long enough to ensure easy placement once the concrete arrives at job site can be difficult. This study is the experimental study on the high-flowing and engineering properties of high flowing concrete using river sand and crushed stone according to the replacement percentage of fly-ash. As a results of this study is the mix proportion of replacement percentage of fly-ash 30% better than the others. And it is confirm to possibility of manufacture of the high flowing concrete.
