る。 This device measures the slump of fresh concrete,
That is, in order to measure the amount of height displacement due to the softness of the molded product after filling and molding fresh concrete into a predetermined mold and removing the mold, a fixed measuring piece 3 is used as shown in Fig. 3. On the other hand, with the measuring piece 2 positioned on the opposite side, the measuring rod 1 is stood vertically, and the measuring piece 2 is moved down so that it comes into contact with the top surface of the molded product a to be measured to measure the height h. Therefore, the index position on the measuring piece 2 side with respect to the slump scale of the measuring rod 1, for example, the measuring piece 2
The amount of displacement in height h before deformation and after deformation due to softness is directly read by the slump scale S using the lower edge line.
