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:
