In this study, for the purpose of producing super flowing concrete which has over 800㎜ slump flow, we discussed the effect of particle size distribution of binder on concrete flow properties. Firstly, we analyzed particle size distribution of six cases which were used as a concrete binder. Namely, we regarded the first class portland cement as a base, and used 6 cases which were combined with limestone powder and fly ash at a regular proportion. We analyzed the flow and rheology in the condition of cement paste. After that, we examined the applicability of batch plant in concrete condition. As a result of particle analysis, the cement and fly ash have rare particle which has over 50㎛, but the limestone powder has 23 precent proportion .So we can find the fact that the limestone powder has the wider range of particle size distribution than that of the cement and fly ash. It was found that the more limestone powder proportion was added, the higher the paste flow increased. From this study, we can find the biggest flow property in the case of the most mixed binding of limestone powder. At that time, the plastic viscosity is 4.20㎩?s, and the yield value is 0.10㎩. On the basis of the optimal binder proportion derived from the previous study, we examined the applicability of batch plant. From the test results, we can make a new type of super flowing concrete of over 800㎜ slump flow which has excellent resistance against segregation. The super flowing concrete used in this study has 58.99㎩?s plastic viscosity and 21.83㎩ yield value. This result shows big differences compared with existing high flowing concrete.
