Abstract

Selected rocks including Sandstones, Limestones, Siltstone, Dolomite and Marl from Salt Range area of Pakistan were subjected to a comprehensive testing program aimed at establishing possible correlations between uniaxial compressive strength (UCS) and Schmidt hammer rebound number (Rn). The study shows that two rock groups having distinct correlations between UCS and Rn exist. The rock groups identified in this study are different from the groups found in a companion study on the same rocks correlating UCS with Point Load Index by Akram and Abu Bakar (2007). The developed correlations were evaluated statistically and were found to be significant at the chosen level of significance.
