FAQ

How should I apply impact angle correction to my rebound hammer test result?

Here it is necessary to differentiate between classical rebound hammers (R-value) and the Silver Schmidt hammers (Q-value). Classical rebound hammers require an impact angle correction when the impact is not carried out...

Which conversion curve should I use with my rebound hammer?

There is no simple answer to this question.
The answer depends on the region you are in and the standards you are working to. In China for example there are standardized correlation curves, which may be selected in the...
