2021-5-1 · In general, the range of crushing zone caused by plastic deformation or shear failure of rock is less than 3 times the borehole radius, and the outside is the fracture zone by tensile failure of rock. The crack can be triggered when the tangential tensile stress generated by blasting stress wave is greater than the rock tensile strength.

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. …
