Allowable Compressive Stress For Granite. Dry or wet conditions as per load determine the compressive strength of the stone. Material compression strength σ tension strength σ psi mpa psi mpa. Compressive strength flexural strength modulus of rupture are sometimes performed using wet stone specimens.
So compressive strength is the highest load per unit area borne by the stone without giving in. Since the strength may vary when the stone is wet the strength tests i e.
Compressive strength flexural strength modulus of rupture are sometimes performed using wet stone specimens.

The allowable bearing pressure for supporting soil and rock at or near the surface shall not exceed the values specified in table 1804 1 unless data to substantiate the use of a higher value are developed and contained in the engineer s geotechnical report and the commissioner approves such value allowable bearing pressure shall be considered to be the pressure at the base of a foundation in.
