blue granite tiles is used for interior walls, columns, floors, stair steps, etc. in large public buildings such as shopping malls, libraries, airports, and stations. Blue granite is more distinguished in natural granite.the blue granite tiles that we commonly see on the day have Blue Pearl,Ice Blue,Butterfly Blue and so on.
Although Blue Granite has become the most commonly used stone in buildings, everyone seems to have a lot of deficiencies in its understanding. Natural blue granite: Its main mineral composition is feldspar, quartz and mica. Its structure is compact, its pores are small, and it has the characteristics of wear resistance, frost resistance and weathering corrosion resistance. Marble in the air will soon react with water and carbide in the air, losing luster and roughening, while granite has strong weathering resistance, both indoor and outdoor decoration.
The granite structure is compact, with high compressive strength, low water absorption, high surface hardness, good chemical stability and durability, but poor fire resistance.
The blue granite is a granular structure with fine, medium or coarse grains, or a plaque-like structure. The particles are uniform and fine, the gap is small (the porosity is generally 0.3% to 0.7%), and the water absorption rate is not high (the water absorption rate is generally From 0.15% to 0.46%), it has good frost resistance.
The hardness of blue granite is high, its Mohs hardness is about 6, its density is between 2.63g/cm3 and 2.75g/cm3, its compressive strength is 100-300MPa, and fine-grained granite can be up to 300MPa or more. Generally in 10 ~ 30Mpa. Granite is often produced in the form of rock foundations, rock strains, rock blocks, etc., and is controlled by regional geodetic structures. Generally, the scale is relatively large and the distribution is relatively wide. Therefore, it is easy to mine, easy to produce large materials, and its joint development is regular. It is conducive to the mining of stone with shape rules.
Blue granite has a high rate of desertification and can be processed in various ways. Also, granite is not easily weathered and can be used as an outdoor decorative stone. Granite has a uniform texture, although the color is mainly light, but it is also rich in red, white, yellow, green, black, purple, brown, beige, blue, etc., and its color changes little, suitable for large The use of the area.
