The Characteristics Of Granite

Granite is a unique material, the physical characteristics of which are mainly the following porous/permeable: the physical permeability of granite is negligible, in 0.2%-4% thermal Stability: Granite with high strength of heat stability, it will not change because of the external temperature changes, Granite has a high density and does not change due to changes in temperature and air composition.

Granite has a strong corrosion resistance, so it is widely used in the storage of chemical corrosion products ductility: Granite extension coefficient range 4.7x10-6-9.0x10-6 (inch x inch). Color: granite color and material are highly consistent hardness: Granite is the most hard building material, also because of its super hardness and make it have very good wear resistance.

Ingredients: Granite mainly consists of quartz and orthoclase and micro-plagioclase feldspar, the most original granite mainly by the following three parts: Feldspar quartz biotite. The proportion of the composition is generally determined by the color and material, but generally the proportion of feldspar is 65%-90% quartz 10%-60% biotite $number.
