Concrete Test Hammer

The Concrete Test Hammer CONCRETO N is different from other N-type hammers, thanks to new and more accurate correlation curves.
The tracking of these curves was obtained by subjecting a non-destructive testing (determination of the indices sclerometric and speed of propagation of ultrasonic pulses) and destructive tests (crushing the press) 50 cubic specimens (200 mm square) of 20 distinct classes of conglomerate for A total of 1000 samples. Based on the results obtained through experimentation on the concrete, the mechanical hammer CONCRETO N, used correctly and according to the procedures, represents a valuable tool for monitoring and estimating the quality of the concrete for maximum reliability of results.

Further details
Reliability and careful selection of components, ten years proven experience as manufacturer of NDT instruments, the distinctive ergonomic and functional design, as well as the continuous scientific research in collaboration with the most important Universities in Italy, has brought to the development of this series of instruments of the latest generation.
The N type Test Hammer – Novatest design – has been modified to get a higher degree of reliability as far as correlation curves are concerned, obtaining the new SonReb method.
To develop new curves, 50 cubic samples (200x200mm) of twenty distinct classes of concrete have been tested. The samples have been subjected to Non-Destructive Tests (hammer indexes and ultrasonic pulses propagation) and Destructive Tests (press-crashing). By analyzing the results of the tests, it has been assessed that the CONCRETO N mechanical concrete test hammer is an invaluable tool to check and estimate the quality of concrete.
Maximum reliability is achieved upon strictly following the manufacturer’s instructions.
