Granite stone has a fine structure, relatively high compressive strength, low water absorption, high surface hardness, good chemical stability, and strong durability, but its fire resistance is poor.
Granite has a fine-grained, medium-grained, coarse-grained granular structure, or a porphyry-like structure. Its particles are uniform and fine, with small gaps (porosity is generally 0.3% ~ 0.7%), water absorption is not high (water absorption is generally 0.15% ~ 0.46%), and it has good anti-freeze properties.
Granite stone has a high hardness, with a Mohs hardness of about 6 degrees, a density between 2.63g/cm3 and 2.75g/cm3, and a compressive strength of 100-300MPa. Among them, fine-grained granite can be as high as 300MPa or more. Its bending strength is average. At 10~30Mpa.
Granite stone is often produced in the form of bedrock, rock strains, rock blocks, etc., and is controlled by the regional geotectonic structure. Generally, they are large in scale and widely distributed, so they are easy to mine, easy to produce aniseed, and have regular joint development. Helps in mining regularly shaped stones.
Granite stone is not easily weathered and can be used as an outdoor decorative material. Granite has a uniform texture and texture. Although the colors are mainly light, red, white, yellow, green, black, purple, brown, beige, blue, etc. are also abundant, and the color does not change much, making it suitable for large buildings. area used.
