Rebound Hammer for Concrete Strength, 10-60 MPa

The concrete rebound hammer is made of stainless steel and has a highly flexible and wear-resistant housing, with an even friction between the pointer shaft and the pointer slide for accurate indexing. ATO concrete rebound hammer is easy to use and simply strikes the concrete surface with the tester's impact plunger and the unit automatically calculates the compressive strength based on the rebound distance.

Applications

The rebound hammer is a widely used non-destructive testing tool for assessing the strength and consistency of concrete structures. It is commonly used in construction and civil engineering applications to evaluate the compressive strength of concrete in areas such as bridges, dams, buildings, and pavements.

Tips: What is the principle of rebound hammer test?

The rebound hammer test is a non-destructive testing method used to determine the compressive strength of hardened concrete. The principle behind the test is that the rebound of a mass hitting a concrete surface is related to the surface hardness of the concrete.

In this test, a spring-loaded mass, called the hammer, is held against the concrete surface, and released. As the hammer strikes the concrete, it rebounds, and the rebound distance is measured by a calibrated scale on the hammer. The rebound distance is then used to calculate the surface hardness of the concrete.

The surface hardness is related to the compressive strength of the concrete, so by measuring the rebound, an estimate of the compressive strength can be obtained. However, the rebound hammer test is only an approximation of the compressive strength, and the test results can be affected by a number of factors, such as the surface condition of the concrete and the moisture content of the concrete. Therefore, the rebound hammer test should be used in conjunction with other tests to obtain a more accurate estimate of the concrete's compressive strength.
