Granite Physical Properties
|Hardness||-||6 to 7 on Moh's Scale|
|Density||-||2.6 to 2.8 Kg/cm3|
|Compressive Strength||-||140 to 210 N/mm2|
|Modulus of Rupture||-||15 to 25 N/mm2|
|Average Wear||-||Less then 1%|
This hard rock has almost negligible porosity ranging between 0.2 to 4%.Thermal Stability
Granite is highly thermal stability and is impervious to weathering from temperature. Even air borne chemicals have no effect on it. It is highly resistant to chemical erosion making granite useful for making tanks to store highly caustic material.
Co-efficient of expansion
The co-efficient of expansion for granite varies from 4.7x10-6 – 9.0x10-6(inch x inch).
Granite has high consistency in color and texture.
Hardness of granite lends it excellent wear, making it excellent building stone.

|FeO||-||1.68% (1.5 - 3%)|
|Fe2O3||-||1.22% (1 - 2%)|
|MgO||-||0.71% (0.5 - 2%)|
