[0002] The tensile strength of concrete is much smaller than its compressive strength, and its ultimate tensile deformation is very small. It is easy to crack under the influence of external forces, temperature changes, humidity changes, etc. Cracks in concrete and reinforced concrete will affect the integrity, durability, and even safety and stability of the building. Cracks can be divided into three categories: stress cracks, shrinkage cracks, and temperature cracks. Relevant detection devices are needed to detect the crack resistance of concrete. Prestressed concrete poles are used in buildings or similar structures. They are made of concrete and have internal reinforcement. They are mainly used for overhead transmission lines above 35 kV.
