Free-free resonance method for the mechanical characterization of carbonate rocks used as building stones

Nondestructive testing techniques have attracted growing interest in the last few years due to their ability assess material properties without damaging specimens. The free-free resonance method is a nondestructive technique based on analysis of natural frequencies sample. This study presents and discusses applicability this technique, traditionally used soils, for mechanical characterization rocks. With aim, obtain dynamic elastic modulus shear four carbonate rocks that been widely as construction materials southern Spain. results from evaluation dry saturated rocks, combination with petrographic uniaxial compression tests, make it possible existing relationships between evaluate impact porosity moisture content behavior.
