Description

Technical Field

[0002] Civil engineering is a discipline that applies scientific and engineering principles to design, build and maintain various types of infrastructure. It includes not only the design and construction of buildings, but also involves many aspects such as roads, bridges, tunnels, water conservancy and environmental engineering. Material strength testing is a process of evaluating the mechanical properties of materials by applying external forces and measuring the stress and strain of materials. This process provides a reliable basis for the design and engineering application of materials.

[0003] Precast concrete parts are needed in civil engineering. When precast concrete parts are produced, the strength of the materials needs to be tested and the compressive resistance of the materials needs to be tested.
