The purpose of this study is to investigate the statistical relationship between hardness value and physicomechanical properties of constructional and cover rocks. The definition, measurement of hardness and classification of the rocks used are very important in construction sector. From this point of view, rock hardness is one of the most important parameters for the determination of rock properties. In this study, the determination of hardness and the physicomechanical properties of constructional and cover rocks in Cukurova region was accomplished using various methods in the laboratory. Statistical relations between physicomechanical properties and hardness of rocks were also determined. High correlations were found between the hardness methods (Shore Scleroscope, Schmidt hammer hardness), which are cheap and easy to use, and other physical and mechanical properties. It was found that physicomechanical properties can be estimated using hardness methods and compared with the calculated value from different empirical equations. (C) 2003 Elsevier B.V.
