The Schmidt hammer is one of the most common and widely used impact tools, which can be a valuable tool when used correctly. But carelessness and use without identifying the effective parameters can lead to incorrect results. Schmidt hammer is a fast, low-cost and non-destructive method both in the laboratory and on site. This method cannot be used as a substitute for the standard compressive strength test, but it is a method to determine the uniformity of concrete in the structure or to compare the change of concrete quality in different parts of a structure. This test is sensitive to local changes in the type of concrete, for example, the presence of coarse particles, just below the piston, causes a low result. In addition, the energy absorbed by concrete is related to its strength and hardness, so that the combination of strength and hardness controls the performance. The Schmidt hammer test only measures the surface properties of concrete. Due to the local dispersion of concrete hardness in a small area, the stiffness numbers should be determined in a number of points close to each other and then averaged from their results.
