Compression test of stone elements

The test consists in sampling an adequate volume of natural stone from a stone element used in the building or artefact under study, which is subsequently cut with precision grinding to form a prism of 50x50x50 mm or 70x70x70 mm, subsequently sent to a state-authorized laboratory for carrying out compression tests until crushing. To correctly characterize the stone sample subjected to compression testing, especially in case of sedimentary rocks, the prismatic samples should be obtained both in a direction parallel and orthogonal to the anisotropy planes of the stone.
