### Natural stone strength compression bending and abrasion

So compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1 800 psi 12.45 MPa and 19 000 psi 131 MPa means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test
