The pressure sensor 5 is used for detecting a pressure value, the pressure value is displayed on the display screen through the control unit, when the concrete test block is broken, the pressure value returns to zero at the moment, the control unit controls the hydraulic cylinder 2 to stop working and records the maximum pressure value transmitted by the pressure sensor 5, the maximum pressure value is the maximum shearing force value which can be borne by the concrete test block, and the maximum shearing strength of the concrete test block can be calculated according to the maximum shearing force value.
While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
