The invention provides a concrete
cracking whole-process simulating tester which comprises a base. The base is provided with an environment box, a concrete test piece containing device, a real environment simulating
system and a loading
system, wherein the environment box is separated from a surrounding environment, the concrete test piece containing device is arranged in the environment box and comprises a fixed chuck, a movable chuck and a test piece middle fixing side template, a concrete test piece containing space is spliced, the fixed chuck is fixedly arranged in the environment box, the movable chuck is movably arranged, a temperature sensor is arranged in the environment box and the concrete test piece containing space, the real environment simulating
system at least comprises a temperature regulating device which is arranged in the environment box and the concrete test piece containing space and simulates the set real environment on the aspect of temperature, the loading system makes the movable chuck fixed or move in the axial direction, a displacement / deformation sensor is arranged on the movable chuck and used for sensing the deformation of a concrete test piece, and a
stress sensor is arranged for sensing the loads borne by the test piece. The whole development process of the temperature, stress and other factors of concrete can be tested under changeable environment conditions from the perspective of tests.
