The physical properties and application fields of granite are described as follows:
The physical properties of granite
Granite is a kind of stone with unique physical characteristics, which is reflected in the following aspects:
1. Low permeability: The physical permeability of granite is extremely low, usually between 0.2% and 4%, which makes it have excellent pollution resistance and weather resistance.
2. High thermal stability: Granite has high thermal stability and will not change due to changes in external temperature, so it is suitable for high temperature environment.
3. High compressive strength and hardness: Granite has high compressive strength and high hardness, its compressive strength can reach 100-300MPa, and even the compressive strength of fine-grained granite can exceed 300MPa, and the Mohs hardness is about 6, which makes it able to withstand greater pressure and wear.
4. Low water absorption: The water absorption rate of granite is usually low, generally between 0.15% and 0.46%, which helps to keep its interior dry and prevent freeze-thaw damage.
5. Good chemical stability: Granite has strong corrosion resistance, so it is widely used in the reserve of chemical corrosion products.
6. Density of granite: It varies depending on its composition and structure, but is usually between 2.6g/cm³ and 3.1g/cm³. This density range makes granite a hard, heavy stone. The higher the density of the stone, the better, so that the higher the accuracy of the product, good stability of the stone is suitable for precision instruments and equipment.
Second, granite can be used in the field
Because of its unique physical properties and beautiful appearance, granite is widely used in many fields:
1. Architectural decoration: Granite is often used as building materials, such as the ground, walls, doors and window frames, pillars and other decorative materials, its hard, durable, beautiful characteristics make it the first choice for large building exterior wall decoration, architectural use will generally choose gray granite.
2. Road construction: Coarse granite is widely used in road paving because of its hard, durable and non-slip characteristics, which helps to improve the safety and service life of roads.
3. Kitchen countertops: Granite is very suitable for kitchen countertops because of its hardness, wear resistance and anti-fouling, which can withstand high pressure and weight while being easy to clean.
4. Handicraft carving: Granite has a delicate texture and hard texture, suitable for sculpture production, such as garden landscape sculpture, figure sculpture and so on.
5. Precision equipment field: in the industrial selection of granite will generally choose natural black granite, its black granite physical properties are more excellent, can be used in precision equipment, a variety of machine tool equipment, metering equipment and aerospace, semiconductor equipment and other related industries.
6. Other fields: Granite can also be used for the construction of DAMS, breakwaters, and the production of tombstones and monuments.
To sum up, granite has become a popular stone material because of its unique physical properties and a wide range of applications.
