Concrete Test Hammer / Sclerometer

The concrete test hammer or sclerometer from PCE-Instruments is used for the non-destructive compression strength measurement of concrete. In such a way, concrete is tested for its load-bearing capacity and strength.The measuring principle is such that the concrete test hammer hits the concrete. Depending on the concrete hardness, the body rebounds, more or less. The rebound is measured by the device and can be converted to a compressive strength.

Since a conventional measurement cannot be carried out in the laboratory when the concrete is built-in, a concrete test hammer is used on site. The measurement is carried out directly on the surface of the concrete and is determined with the help of a conversion table for compressive strength classes. The compressive strength is determined by means of a one-axis, short pressure load without damaging the concrete. The compressive strength of concrete depends on various influence factors such as granules size, water-cement value, fresh concrete density, air content in concrete, resistance to chemical attacks etc.

The strength classes for standard and heavy aggregate concrete refer to the test specimens, which have been stored up to the test age of 28 days either under water or at a relative humidity of 95%. With the sclerometer PCE-HT 225E, the measured parameters are converted directly in the device and then output and, in addition, the data can also be transmitted from the device to a PC.

The concrete rebound test hammer is an analog measuring device to determine concrete strength. The measuring method of the concrete rebound test hammer is based on the Schmidt principle. With this measuring method, a kinetic impact energy hits the concrete from the concrete rebound test hammer. The resulting rebound enables the concrete rebound test hammer to determine the strength of the concrete.

Nominal kinetic energy: 4.5 J
For high-strength concrete
Simple and quick operation
For determining concrete hardness
