The use of rocks in construction is governed by standards that require a series of chemical criteria, mineralogical-petrographical and physical-mechanical that they must meet. The execution of various works is permitted only if they fall within certain quality criteria. In this context, the geo-mechanical properties were determined for Căzănești gabbro and Căzănești diabase, which were compared with the conditions of admissibility imposed by current standards, for use in different areas. To get a more detailed view of geomechanical properties of the ophiolitic rocks it was required a classification based on three criteria: chemical, geological and geo-mechanical. The chemical criterion of rock classification is based on the content of SiO2 and alkali-aggregate reaction. From the geological point of view, there were chosen for classification purposes those features that could provide information on strength and deformation behavior. The geo-mechanical classification criterion employed in this paper was in accordance with standards widely used today, trying to characterize the analyzed ophiolitic rocks in terms of physical characteristics, strength and deformation.
