Granite is a kind of tectonic rock formed by volcanic erupting lava that rises to the surface of the earth's crust in a molten state under considerable pressure. The magma does not spray out of the ground, but slowly cools and solidifies underground. Granite also includes high load-bearing capacity, compressive resistance and good abrasive ductility. It is also easy to cut and shape, and it can create thin slabs. So what are the uses of granite stone? Next, let's take a look at Xiaobian FABULOUS.
General purpose:
The unique physical properties of granite coupled with its beautiful patterns make it a good material for construction. It is known as the "King of Rocks". Some people use one view, two measurements, three listenings, and four tests to evaluate the quality. Granite can be used from the roof to the floor in the building, as is the curb of the sidewalk. If it is crushed, it can be made into a cement or rock-filled dam. Many places or objects that need to be resistant to wind and rain or need to last forever are made of granite. The sign of Taipei’s "Chiang Cheng Memorial Hall" and the Monument to the People’s Heroes in front of Tiananmen Square in Beijing are made of granite. The granite's enduring characteristics after a thousand years is proven by the famous Egyptian pyramids.
The granite has uniform structure, hard texture and beautiful color. It is a high-quality building stone. The compressive strength varies according to the type of stone and the place of origin, about 1000-3000 kg/cm. Granite is not easy to weather, the color is beautiful, and the appearance and color can be maintained for more than a hundred years. Because of its high hardness and wear resistance, it is not only used for high-level architectural decoration projects and hall floors, but also the first choice for open-air carving.
business use:
Commercial granite includes granite and gneiss. Gneiss rocks include mineral composition, granite-like and granular crystal structure. Commercial granite also includes other similar structures and feldspar crystalline rocks with a small amount of accessory minerals, which are mainly used for decoration, such as plagioclase as petrologists call it. Gneiss is a rough crystalline rock, mainly composed of silicate minerals, showing mosaic and granular crystalline structure. Different types of minerals are arranged regularly or irregularly.
According to the American Society for Testing and Materials, granite is classified into ordinary granite and black granite. Ordinary granite is composed of quartz, feldspar, marble, etc., and is black or dark green due to colored minerals. Generally speaking, its color is often influenced by feldspar. The dark green or black rock of black granite is formed by plagioclase, pyroxene, olivine, and hornblende. Therefore, black granite is divided into three types: porphyrite, diabase, and basalt.
