Correlations Between Mechanical and Index Properties of Sandstone from the Central Salt Range

Abstract

A study was conducted to uncover the possible correlations among mechanical and index properties of sandstones from formations of Salt Range area, Punjab, Pakistan. For this purpose, sandstone block samples were collected from seven formations of the Salt Range. The samples were prepared for rock testing according to the guidelines set by International Society of Rock Mechanics (ISRM). Defective samples were discarded and those meeting the ISRM specifications were tested for sonic velocities, dry density, porosity, uniaxial compressive strength, tensile strength and elastic constants. Results obtained were then statistically analyzed to find the predictive relationships. The analysis revealed that correlations exist between two groups of tested rocks. The predictive relationships were determined between porosity and static mechanical properties of rocks and between porosity and dynamic mechanical properties.
