かつ万遍なく充填することが難しくなる。When manufacturing prestressed concrete by such a post-tensioning method, the viscosity of the cement grout material 5 filled in the through-hole 2 is important. That is, if the viscosity of the cement grout material 5 is small, the work of filling the cement grout material 5 into the through-hole 2 is easy, but the cement grout material 5 has a "first" This causes a “flow” phenomenon, which causes a void to be formed in the through-hole 2.
If the viscosity is large, the fluidity of the cement grout material 5 is low, and thus, the above-mentioned filling operation cannot be performed smoothly,
Alternatively, it becomes difficult to uniformly and evenly fill the cement grout material 5 into the through holes 2.

In this method, the flow-down opening is opened to allow the cement grout material to flow down, the flow time of the cement grout material at this time is measured, and the viscosity is measured using the flow time as a parameter of viscosity.

It is difficult to determine the timing of the occurrence of the measurement, and therefore, the measurement result greatly depends on the skill of the measurer.

The weight of the storage container 12 increases linearly from the start of the flow of the viscous fluid, and when most of the viscous fluid L in the measuring container 11 flows down, the above-described increase in the weight is extremely reduced.
This is due to the fact that the viscous fluid L flowing down becomes sharply tapered at the end of the flow of the viscous fluid L due to the narrow flow-down port 14 of the measuring container 11, and the amount of the viscous fluid L flowing down into the storage container 12 is extremely reduced.
