Engineers and architects can create structures that require less material while still achieving the same structural performance as traditional concrete. The concrete enhanced with graphene is 2.5 times stronger than standard concrete, has a water permeability 4 times lower, and uses less cement to provide the required strength.

A glass plate 101 is fixedly connected to the middle of the heat insulation door 22.

A magnet 24 is fixedly connected to the right side of the constant temperature box 1, and the magnet 24 is magnetically adsorbed to the heat insulation door 22.
[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, the fixing mechanism includes a turntable 4, a screw 5, an annular block 6, a driving block 601, a guide rod 602, a lifting block 7, a zigzag block 8 and a fixing plate 9. A turntable 4 is rotatably connected to the top of the constant temperature box 1. A screw 5 is welded to the bottom of the turntable 4, and the screw 5 penetrates into the middle inside the constant temperature box 1. An annular block 6 is rotatably connected to the lower part of the turntable 4, and the annular block 6 is fixedly connected to the upper part inside the constant temperature box 1. Driving blocks 601 are symmetrically rotatably connected to the left and right sides of the annular block 6. Zigzag blocks 8 are symmetrically rotatably connected to the lower parts of the two driving blocks 601, and both of the two zigzag blocks 8 are slidably inserted and connected to the fixing blocks 10. A lifting block 7 is connected between the two zigzag blocks 8. The left and right sides of the lifting block 7 are rotatably and slidably connected to the zigzag blocks 8, and the lifting block 7 is threadedly connected to the screw 5. Two guide rods 602 are fixedly connected between the fixing blocks 10 and the annular block 6, and the lifting block 7 is slidably connected to the two guide rods 602.

[0025] When the anti-cracking performance of graphene concrete needs to be detected, this device can be used. First, the staff needs to prepare a trash can and place it at the rear end of the hose 18. Then, the staff rotates and opens the heat insulation door 22 through the door handle 23, and the stopper 102 no longer blocks the bearing plate 2. Then, the staff pulls the bearing plate 2 forward through the pull rod 3, places the graphene concrete to be detected in the groove on the bearing plate 2, then pushes the bearing plate 2 and the graphene concrete back to the original position, while keeping the graphene concrete in the exact middle of the two fixing plates 9, and closes the heat insulation door 22. Then, the staff needs to rotate the turntable 4 counterclockwise, which drives the screw rod 5 to rotate. The rotation of the screw rod 5 drives the lifting block 7 to move upward, and makes the two zigzag blocks 8 approach the two fixing plates 9, and finally clamps and fixes the graphene concrete.
[0026] Next, if it is necessary to simulate the anti-cracking performance of graphene concrete in multiple environments, the staff can adjust the working efficiency of the humidifier 13 and the temperature controller 14 through the controller 12 to keep the temperature in the constant temperature frame 1 at the same temperature. After adjustment, the staff can start the hydraulic press 11 to conduct a compressive test on the graphene concrete, and then observe and record the anti-cracking performance of the graphene concrete. After the test, the staff needs to rotate the turntable 4 clockwise so that the fixing plate 9 no longer clamps the graphene concrete. Then, the heat insulation door 22 can be opened and the bearing plate 2 can be pulled to take out the graphene concrete. After the compressive test, some debris will fall off the graphene concrete. The staff can first start the vacuum cleaner 17, then move the heat insulation plate 19 upward so that the heat insulation plate 19 no longer blocks the U-shaped block 15. Then, the U-shaped block 15 is pulled forward through the handle 16, and the elastic member 20 is compressed. At the same time, the vacuum cleaner 17 will clean the debris on the bearing plate 2 and suck it into the trash can. After cleaning, release the handle 16 and turn off the vacuum cleaner 17. The elastic member 20 will automatically reset and drive the U-shaped block 15 to reset. At the same time, the heat insulation plate 19 will also automatically drop and reset due to gravity. Thus, a round of anti-cracking performance detection of graphene concrete is completed. Repeating the above steps can continuously detect the anti-cracking performance of graphene concrete.
[0027] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
