コンクリートの管内流動に関する研究

抄録

For the purpose of streamlining the concrete pumping work, the author proposes an equation for predicting the pipe flow of concrete as a result of theoretical and experimental studies on the flow of concrete in piping. In addition, the author also proposes an inclined pipe testing method capable of simply estimating different factors used for the calculation using the enuntion. Furthermore. on the basis of studies of pressure losses in bends and vertical piping, the author introduces a practical calculation program for approximating the pressure required for transfer of concrete through piping under pressure.
