At present, it is very important to use the rebound method to detect the construction quality of concrete structures in construction projects.
The principle is mainly based on the hardness and strength of concrete.
Under the action of elasticity, the impact force of the steel hammer is transmitted to the surface of the concrete, and the initial function is redistributed.
In the case of plastic or residual deformation, the concrete absorbs some of its capacity, and other capacities will reach the heavy hammer to ensure the rebound height of the steel hammer.
Combined with the positive correlation between this height and the strength of the concrete, the strength of the concrete material itself can be effectively calculated.
