Concrete of qualified quality is an important factor to ensure the qualification of buildings. When judging whether the concrete is qualified or not, we Generally, its compressive capacity will be tested. Compressive capacity refers to the strength limit when external force is pressure. In sedimentary rocks, its compressive strength is mostly determined by the properties of cements. Taking sandstone, conglomerate and breccia as examples, usually The compressive strength test of building concrete is carried out in the laboratory. The material needs to be placed on the test table for fixing, and then the material is squeezed by the hydraulic loading mechanism. When the material is broken, it is easy to hurt the staff. Traditional The detection device is inconvenient to move and does not have a strong fixation effect on the material.
