Allowable Compressive Stress For Granite

Compressive strength flexural strength modulus of rupture are sometimes performed using wet stone specimens.

Allowable compressive stress for granite.

Dry or wet conditions as per load determine the compressive strength of the stone. If is often measured as the maximum stress the material can sustain under. 8 10 8 4 theory of strength. 8 1 compressive strength the strength of a material may be broadly defined as the ability of the material to resist imposed forces.

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. For the dry condition the stone specimens are dried in an oven at 60 c 2 c 140 f 2 f for at least 48 hours or. The characteristic compressive strength of stone masonry with bed joints 10 mm thick or less and in mortar designation iii or stronger may be taken as 0 35 times the mean compressive strength of the natural stone masonry units or representative cubes when prepared in accordance with bs en 771 6 and tested in accordance with bs en 772 1.
