Is there any standard for granite building panels

Hello, granite has different uses depending on the size of the grain: the fine grain can be polished or carved as a decorative plate or a work of art; Medium-grained ones are often used in the construction of bridge piers, arches, embankments, harbors, legs, foundations, pavements, etc.; The coarse grains are rolled into crushed stone, which is an excellent aggregate for concrete. Because granite is acid-resistant, it is also used as acid-resistant lining and container in chemical and metallurgical production.

It is also used as a raw material for building materials, interior decoration materials, and carved artworks.

Granite is a --- magmatic rock or igneous rock. According to the geological genesis, rocks can be divided into three categories: igneous rocks, sedimentary rocks and metamorphic rocks. Granite belongs to igneous rocks (magmatic rocks), limestone belongs to sedimentary rocks, and marble belongs to metamorphic rocks.

Granite is mainly composed of quartz, feldspar, amphibole, pyroxene, olivine, mica and other mineral components. The Mohs hardness is above 6 degrees, and the shore hardness is between 60 and 90, and the luster and color have a great relationship with the mineral composition contained in it, which can be described as ever-changing.

Granite is a plutonic acid igneous rock formed by the condensation of magma deep underground, and some granite is gneiss or mixed lithified rocks formed by metamorphism of magma and sedimentary rocks, mostly light flesh red, light gray, grayish white, etc. Its etymology is the Latin word granum, which means granular. Because of its hard texture and beautiful color, granite is not only a good building material, but also the first choice for open-air carving.

Granite belongs to the building material.

1. Amphibole granite is the darkest granite variety and is suitable for all kinds of weather, so it is suitable for any use.

2. Biotite granite has a variety of colors and is one of the most widely used granites in construction. It is the hardest of all granites and is suitable for both indoor and outdoor use.

3. Talc granite is one of the least known forms of granite because it does not resist natural forces (wind, rain) very well. This makes it less suitable for use as flooring, countertops, and outdoors, and is only used for decorative purposes.

4. Electrical granite has a variety of colors, except for colorless and white, which is extremely rare. This granite type is ideal for places without a lot of traffic, as it is soft for all types.
