Properties of Rocks | Geology
Two rocks of the same type with the same resistance to crushing can offer different resistances to attrition. The resistance of a rock to fracture is approximately 1/10 to 1/30 of the ultimate resistance to crushing. Some physical and mechanical properties of rocks, important in technology are given in table-7.

Aggregate Crushing Value Test -Determine Aggregate Crushing Strength
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.

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

compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material.
