Sandstone is a sedimentary rock, mainly composed of a variety of sand cement, particle diameter of 0.05-2mm, which sand content of more than 50%, stable structure, usually light brown or red, mainly silicon, calcium, clay and oxidation iron. The vast majority of sandstones are made of quartz or feldspar
Sandstone is the source area of the rock by weathering, erosion, handling in the basin in the accumulation of formation. The rock consists of debris and interstitial parts. Debris Common minerals: quartz, feldspar, muscovite, calcite, clay minerals, dolomite, oolitic chlorite, chlorite and so on. The interstitial material includes both the cement and the debris. Common cements have siliceous and carbonate cementation; the heterogeneous component mainly refers to the finer clay or silt material that is deposited simultaneously with the debris.
The sandstone is a sedimentary rock that is precipitated from the stone by water erosion on the riverbed, and since the accumulation of thousands of years has become firm. After the earth's crustal movement, and the formation of today's mines. Although China's sandstone varieties are very much, but the main is concentrated in Sichuan, Yunnan and Shandong, which is the three major producing areas of sandstone in China, while Hebei, Henan, Shanxi, Shaanxi, etc., but the product is not high visibility, influence Smaller.
⑴ Features: sandstone, noise, moisture absorption, anti-damage, outdoor weathering, water does not melt, not long moss, easy to clean and so on. Advantages of sandstone:
⑵ advantages: sandstone is a kind of no light pollution, no radiation of high quality natural stone, the human body without radioactive damage. It is moisture-proof, non-slip, sound-absorbing, light-absorbing, tasteless, no radiation, no fading, Dongnuanxialiang, warm and elegant; compared with the wood, no cracking, no deformation, no rotten, Product installation simplicity, as long as the use of marble glue can be fixed on the wall carvings, the product can be decorated with wood for organic connection, the background shape of the space to play a better, to overcome the traditional installation of stone cumbersome and reduce installation costs. Decorated houses do not need to add other processes and paint can be directly on the carved on the wall.
⑶ material, a warm texture of the decorative materials, elegant and warm, coordinated and yet luxurious; with stone texture, wood texture, as well as spectacular landscape pictures, rich colors, close to nature, simple and elegant, in many Stone in a unique style was the United States that "Li Shi."
Sandstone is the most widely used stone of mankind, its noble and elegant temperament natural environmental characteristics of the achievements of the history of the building blossoming wonderful flowers. Hundreds of years ago decorated with sandstone from the Louvre, the British Royal Palace, the US Capitol, Harvard University, Notre Dame, etc. still still charm still, the classic forever.
Previously, sandstone was very laborious for construction purposes, due to the relatively backward cutting and processing machinery of the quarry. In recent years, these conditions have been improved, and gradually to the highest level of professional knowledge, according to the customer's color requirements to provide customers with high-quality products. Sandstone can be widely used. Some people even think that "people can think of it, it can be used."
