1、 Granite has a dense structure, high compressive strength, low water absorption, high surface hardness, good chemical stability, strong durability, but poor fire resistance.
2、 Granite has a granular structure of fine, medium, and coarse grains, or a porphyritic structure. Its particles are uniform and dense, with small gaps (porosity generally 0.3% to 0.7%), low water absorption (water absorption generally 0.15% to 0.46%), and good frost resistance.
3、 Granite has a high hardness, with a Mohs hardness of around 6, a density of between 2.63 g/cm3 and 2.75 g/cm3, and a compressive strength of 100-300 MPa, of which fine-grained granite can be as high as 300 MPa or more, with a flexural strength generally between 10 and 30 MPa. Granite is often produced in the form of bedrock, rock stock, rock block, etc., and is controlled by regional geotectonics. It is generally relatively large in scale and widely distributed, so it is easy to mine, easy to produce large materials, and its joint development is regular, which is conducive to mining stones with regular shapes.
4、 Granite has a high waste formation rate and can be processed in various ways. The plates have good spliceability. Also, granite is not easily weathered and can be used as outdoor decorative stone. The texture and texture of granite are uniform, and although the color is mainly light, it is also very rich in red, white, yellow, green, black, purple, and so on. Moreover, its color changes relatively little, suitable for use in large areas.
