ASTM Test Results Select Stone
Compressive Strength. Compressive Strength is the stress, in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.
