The Materials Specifications put forth minimum values for compressive strength for each stone type; for example, at least 1,800 psi (12.45 MPa) for marble and 19,000 psi (131 MPa) for granite. Compressive strength—or the load at which the stone fails—is usually much higher than the actual load the stone must resist.Web

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.Web

What is compression force? The compression strength of a material is its ability to withstand external forces that push on it. When a column supports a load from above, it is under compressive stress. On a molecular level, the consequence of that force is that the particles atoms and molecules in the material shorten.Web
