[0017] In the present embodiment, when testing the air entraining performance of the air entraining agent, firstly, concrete with air entraining agent added is poured into the hopper 1, and then the operator can open the discharge valve 3 to discharge the concrete in the hopper 1 into the concrete collecting box 406 through the discharge valve 3. Since the concrete collecting box 406 exerts gravity on the weighing sensor 404 through the moving wheel 407 and the storage plate 405, the external control panel can monitor the weight change of the concrete collecting box 406 in real time through the weighing sensor 404.
