Although gray granite has become the most commonly used stone in buildings, everyone seems to have many deficiencies in its understanding. Natural gray 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 gray granite is a granular structure with fine, medium and 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 0.15% to 0.46%), with good frost resistance.
Gray granite has high hardness, 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 as high as 300MPa or more. At 10 to 30 MPa. 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.
Gray 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.
