Properties

Chemical Properties of Granite

Granite is primarily composed of feldspar, quartz along with various other minerals in varying percentage, which are stated as follows

Silica (Sio2) : 70-77%	Alumina (Al203) : 11-14%	Potassium Oxide(P205): 3-5%	Soda (Na20) - 3-5%
Lime : 1 %	Iron (Fe203) : 1-2%	Iron (Fe0) : 1-3%	Magnesia (Mg0) : 5-11%
Titina : less than 1% (0.38%)	Water (H20) : 0.03%

Physical Properties of Marble

In terms of its physical properties granite is a unique material. These properties lending uniqueness to granite are :

Porosity / Permeability - granite has almost negligible porosity ranging between 0.2 to 4%.

Thermal Stability - Granite is highly stable thermally, therefore shows no changes with the change in temperature. Granite is impervious to weathering from temperature and even from the air borne chemicals. It is the high resistance to chemical erosion that makes granite useful for making tanks to store highly caustic material.

Co-efficient of Expansion - The co-efficient of expansion for granite varies from 4.7 X 10.6 to 9.0 X 10.6 (Inch X Inch)

Variegation - Granite shows consistency In colour end texture.

Hardness - It Is the hardest building stone end hardness of granite that lends its excellent wear.
