For the purpose of the quality assurance of porous concrete (PoC) with continuous voids, it is necessary to control the flow condition of the binder adhering to the surface of aggregate in the vibration. This paper describes the flow characteristic of the binder by Rheological treatment at the fresh stage, since the flow pattern of the binder generally shows pseudo-plastic (pp) flow having a yield value in a state wherein grouting. As the result, it became clear that the flow condition which does not flow down to the bottom in the vibration was given by apparent viscosity and vibrational acceleration.
