[0002] Before ready-mixed concrete leaves the factory, the manufacturer needs to carry out factory strength inspection on the concrete, and the inspection frequency of every 100 plates of concrete with the same mixing proportion should not be less than 1 time. Concrete strength inspection needs to use a concrete mold to form a test block of a corresponding size, and the steps of manually forming the concrete test block usually include pouring, vibration, one-time troweling, two-time troweling, demolding and other processes. During the production process of a concrete mixing station, a large number of concrete test blocks need to be formed every day for strength detection, which results in a large labor intensity of workers and low production efficiency.
