What can granite do besides dry hanging?

Sep 15, 2020

Granite is a kind of tectonic rock formed by volcanic erupting lava in a molten state under considerable pressure and uplifting to the surface of the crust. The magma does not spray out of the ground, but is slowly cooled and solidified under the ground. It is a kind of deep formation. Acidic igneous rock belongs to magmatic rock.


Granite of grain is the meaning of this term, often understood as chloroplasts in Latin, which was made on the structure small granule and the formation of the granite is the most hard stone, granite features advantages include high load bearing, compressive ability, and good grinding ductility, granite is also easy to cut, shape, can create a big plate of sheet etc., all in all, granite with super durable ability.


General purpose:


The unique physical properties of granite plus 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. Granite's enduring characteristics even after a thousand years are 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, beautiful in color, 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 granites include granite, gneiss, granite block gneiss granite, granite schist of Shandong Wulian Qicai Stone Mine, and rocks with the composition of syenite and granodiorite as scholars call them. Gneiss rocks include those with 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, with mosaic and granular crystalline structure. Different types of minerals are arranged in regular or irregular arrangements.


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 rocks of black granite are made of plagioclase, pyroxene, olivine, and hornblende. Therefore, black granite is divided into three types: porphyrite, diabase, and basalt.
