Abstract
The paper presents the results of mechanical laboratory tests of two types of sandstone, white and gray, obtained from two stone quarries in Poland. Compression tests of cubic samples, three-point bending tests, bending of notched beams and quasi-Brazilian test were performed. Basing on these tests, the values of compressive strength, tensile strength, Young's modulus and Poisson's ratio were determined. From the bending test of notched beams, a critical stress intensity factor in mode I and critical energy release rate was determined. These values are intended to be used as parameters of numerical (FEM) model to simulate the pull-out test of an anchor pulled out from the rock surface.
