چکیده
The objective of the current study was to compare results relating compressive and tensile strength rocks obtained during research undertaken according Polish Standards (as part European standards known as Eurocodes), American Society for Testing Materials (ASTM) Standards, recommendations International Rock Mechanics (ISRM). A total 130 experiments uniaxial compression on axisymmetric samples, point loads, transverse (so-called Brazilian tests) were performed rock samples comprising granite, limestone, sandstone. Geometric properties selected depending applied method, relationship between specimen’s slenderness shape, values strength, analyzed. showed that in a laboratory depend significantly specimen slenderness, different which are imposed by various ISRM recommendations, wherein this sensitivity much higher case strength. also raised doubt about usefulness so-called load test method determination potential estimation
