Description

Technical Field

[0002] Concrete, abbreviated as "concrete": refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion and mixed together. Cement concrete, also known as ordinary concrete, is widely used in civil engineering.

[0003] Since concrete is widely used in construction and civil engineering, considering safety issues, the compressive resistance of concrete is of vital importance and is a decisive factor in the quality of civil engineering. The application number is: 202123165109.5, a compressive performance testing device for concrete production, which clamps the concrete to be tested with a plywood and then performs a compressive test. However, the plywood clamps the concrete and reinforces the concrete, which makes the compressive test of the concrete inaccurate and cannot accurately test the compressive grade of the concrete. At the same time, the device also uses a fan and a dust hood to collect the concrete and its concrete slag after compression, but the concrete may be in large lumps, and the fan and dust hood cannot collect large lumps of concrete, resulting in incomplete collection of the concrete, and the staff are required to manually clean it, which increases the labor burden.
