The physical properties of granite
Granite is a unique material, these physical characteristics are mainly the following porous/permeable: the physical permeability of granite is almost negligible, in 0.2%-4% thermal Stability: Granite with high strength resistance
Thermal stability, it will not change because of the external temperature changes, granite because of its high density and will not be due to changes in temperature and air composition. Granite is highly resistant to corrosion and is therefore widely used in the storage of chemical corrosion Products: the extension coefficient range of granite 4.7x10-6-9.0x10-6 (inch x inch).
Color: granite color and material are highly consistent hardness: Granite is the hardest building materials, but also because of its super hardness and make it has a good wear resistance. Ingredients: Granite mainly composed of quartz and orthoclase and micro-plagioclase, the most primitive granite mainly from the following three parts: Feldspar quartz biotite.
The proportion of each component is generally determined by color and material, but generally the proportion of feldspar is 65%-90% quartz 10%-60% biotite 10%-15%
