FAQ

What are the types of granite

This decision to find your favorite color or pattern is much more complicated. Must take into account the best use of each granite. According to the mineral composition, there are several types of facade granite: hornblende granite is the darkest granite variety, suitable for all kinds of weather, so it is suitable for any use. Biomagnetic granites exist in many colors and are one of the most widely used granites in architecture.

What does the granite mean?

Granite structure is uniform, hard texture, beautiful color, is the quality of building stone. Compressive strength varies according to the variety and origin of stone, about 1000-3000 kg / cm. Granite is not easy to weathering, beautiful color, the appearance of color can be maintained for more than a century, because of its high hardness, wear resistance, in addition to the use of high-level architectural decoration works, hall floor, or open-air carving of the preferred material.

How is the granite floor refurbished and maintained?

First, the granite floor renovation needs to refurbish the speed and weight of the machine, grinding the marble refurbished machine but also the effect and the 260 kg granite grinder can not be compared

What is the hardness range of granite?

Granite is igneous, formed by underground magma jet and intrusion cooling, as well as granitic metamorphic rocks, etc. It has visible crystal structure and texture, it consists of feldspar (usually potassium feldspar and amphibole) and quartz composition, Mixed with a small amount of mica (biotite or muscovite) and trace minerals, such as: zircon, apatite, magnetite, ilmenite and stone, etc. Granite is the main component of silica, its content About 65% -85%. The chemical properties of granite are weakly acidic.Often, the granite is slightly white or gray, with the dark crystal, the appearance of the spot with the addition of potassium feldspar Red or flesh. Granite is slowly cooled by the magma and crystallized, buried deep below the surface. When the cooling rate is unusually slow, it forms a very coarse texture of granite, which is called crystalline granite. Granite and other crystal rocks Constitute the basis of the continental plate, it is also exposed to the Earth's most common intrusive rocks.

How the granite is formed

Although granite is thought to be igneous from the melted material or magma, there is a lot of evidence that some granite formation is a partial deformation or a product of a previous rock that is rearranged and recrystallized without a liquid or melting process.

What is the globular weathering of granite and why is it a "globular" strange name?

Spheroidal weathering (spheroidal weathering): the rock was spherical, from the table and the layers of weathering peeling phenomenon. It mainly occurs in granite, diabase and some sandstone. Fracture cutting in different directions, rock, water, gas and various microbial invasion along the cracks, resulting from the table and the layers of weathering peeling. As the surface area of the rock mass is larger, the strength and depth of the weathering are relatively large, so that the part of the rock mass is not subject to weathering. After the ball-like weathering debris material is stripped, the residual spherical rock block is called "stone egg".

Is granite poisonous?

Granite is a volcanic eruption of lava and subject to considerable pressure in the molten state uplift to the crustal surface of the tectonic rocks. It is also considered to be the result of graniteization caused by deep metamorphism and metasomatism. Many non-ferrous metals such as copper, lead, zinc, tungsten, tin, bismuth, molybdenum, precious metals such as gold, silver, rare metals such as niobium, tantalum, beryllium, radioactive elements such as uranium, thorium, etc., are related to granite. Part of the granite will overflow radon, a natural radioactive gas. Radon can cause lung cancer.
