The density, porosity and strength of rocks are fundamental features for geo-engineers to design projects. Determining these properties requires preparation of smooth core samples which is usually impossible for soft rocks. Besides, in order to predict rock properties, samples except fragments might not be present in some projects such as drilling. Therefore, derivation of empirical equations will be useful to predict rock properties from rock particles such as drilling debris. This study was undertaken to develop prediction equations for compressive strength (UCS), tensile strength (BTS), density and porosity from the crushability index (CI) obtained from rock fragments. The results showed that UCS, BTS, density and porosity were strongly correlated with the CI. To conclude, the physical characteristics and strength of rocks may be predicted with the help of the derived equations. The CI test is a valuable method for estimating rock features in drilling projects and in situations where there are not available core specimens.Downloads
