[0002] Concrete is a widely used building material in today's construction field. The quality of its performance directly affects the safety of the building, especially the compressive strength. The compressive strength is measured by making concrete test blocks and placing them on a pressure testing machine. By controlling different pressures, the concrete test blocks are squeezed until they break. In order to improve the safety performance of concrete buildings, three to five concrete test blocks will be poured before laying and construction for multiple compressive strength tests.

[0003] However, in actual operation, the traditional pressure-controlled compressive strength testing device for testing the compressive strength of samples will cause the concrete test block to be squeezed and crushed, and the fragments will be scattered on the workbench. The staff needs to use some cleaning tools to clean the fragments from the workbench, which is time-consuming and labor-intensive, and inconvenient to operate, which increases the workload of the staff and also affects the efficiency of the testing work.
