 Sclerometer or Schmidt Hammer

With this apparatus on-site tests can be carried out which allow us to estimate the resistance of rock to simple compression.

It is widely used as it is easy to transport, permitting a large number of measurements in a short amount of time, and it can be applied both on a rocky matrix as well as on the walls of a discontinuity.

The test measures the rebound resistance of the surface of the rock being tested. This measurement is correlated with the resistance to simple compression of the rock using Miller´s correlative graph.
