The minimum recommendation for a standard quality rating is 1,500 pounds/psi. Ultimately, depending on the modulus of rupture, thicker material may be needed. Results from this test typically run higher than the closely related C880 – Flexural Strength test because it tests the stone in a narrow band.
Sedimentary rocks such as limestone and sandstone can also be used in thin stone wall systems. However, panels fabricated from these stone types are usually not less than 2 inches in thickness because of the lesser strengths of these stones relative to granite and marble. Commercially, limestone refers to rocks that are both limestone and dolomite.
