The Importance of Testing When Specifying Natural Stone
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.
