Jul 20, 2018  A stone floor has to withstand loads of people and heavy objects. 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.

Compressive strength - Wikipedia

When a specimen of material is loaded in such a way that it extends it is said to be in tension. On the other hand, if the material compresses and shortens it is said to be in compression. On an atomic level, the molecules or atoms are forced apart when in tension whereas in compression they are forced together. Since atoms in solids always try to find an equilibrium position, and distance between other atoms, forces arise throughout the entire material which oppose both tension or compression. The phenomena prevailing on an atomic level are therefore similar.

Stone Testing

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. 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

Building Stones: Meaning and Properties Geology

It has been found that in stones, transverse strength is generally 1/10 th to 1/20 th of their compressive strength values. Shear Strength of a stone is also not commonly determined except when the stone is to be used as a column. It has been observed that in important building stones the shear strength lies between 70-140 kg/cm 2. 3. Porosity:
