ABSTRACT

The research included the petrographical analysis of the samples and the petrophysical properties study of the stones, both “in situ” and in the laboratory. Polarized light optical microscope and a fluorescence microscope were used for the petrographical analysis allowing studying the fissuration rate of the samples in depth. The petrophysical characterization was done using ultrasonic wave propagation velocity (Vp)-taking into account the indirect transmission method (in the field) and the direct transmission method (in the laboratory)-, using the sclerometric method for the surface hardness measurement and a 3D optical roughness meter for the characterization of the rugosity. Other petrophysical properties determined included real and bulk densities, compactness, open porosity or porosity accessible to water and water saturation (RILEM 1980).
