Stone Tests
Crushing test. The crushing strength of a stone is the maximum load it can withstand per unit area before failure. It is determined by dividing the maximum crushing load by the area of the stone's bearing face. To assess the crushing strength of stone, samples are cut into cubes measuring 40 x 40 x 40 mm.
