The white stone is a natural stone or artificial?
Travertine shade with a beige majority, and makes people feel warm, rich texture, clear stripes, promote the building decoration often have strong cultural and historical charm, is the use of multiple buildings in the world. Designed by the American architectural firm of Ieoh Ming Pei is located in Beijing Xidan road Bank of China Building decoration on the choice of Italy, Rome stone, a total of 20000 square meters. Why not call it marble, because it is the texture and appearance of the marble in the traditional sense is different, the decoration sector simply on conventional. Its formation is generally considered to be a calcareous material precipitated from a carbonated spring (usually a hot spring) under atmospheric conditions. The specific form is circulating groundwater containing carbon dioxide solution in the factory away a lot of calcium carbonate, when spring groundwater to the surface, some of the carbon dioxide released and condensed in the sedimentary layers of calcium carbonate, formed a rare bubbles (holes), from and with travertine. In the ocean and limestone precipitation is different, travertine ponds mostly in rivers or lakes, quickly deposited, the rapid deposition of organic matter and gas can not be released, and beautiful texture, but the disadvantage is layered it will produce cracks, make it weakened in line with the texture direction of strength. Because of the hole, the density of the tuff is not large, it is suitable to be used as covering material, and is not suitable for the structural material and the basic material of the building. In the past people used a lot of glue as the basis of travertine and structural materials of construction, but the concrete, now not used. In addition to the Yellow travertine, there are green, white, purple, pink, brown etc.. China's Henan has found travertine and output. Travertine is mainly used in building exterior decoration and indoor flooring, wall decoration.
Crude。Called travertine, travertine, English: (Travertine) is a kind of porous rock, so people usually call it travertine. Travertine belongs to continental sedimentary rocks, it is a kind of calcium carbonate sediments. Travertine limestone terrain mostly formed in the calcium carbonate rich, is soluble in water, calcium carbonate and other mineral deposits in the river, lake, and the formation of. Due to the heavy accumulation in the process sometimes appear at the same time pore, the main component of its own and is calcium carbonate, it is easy to be dissolved in water corrosion, so these deposits will appear in many natural irregular holes.Because travertine stone surface has many holes and the name, the name is stone travertine or tufa, commercial, it is classified as a class of marble. The human use of stone in a very long time, the most representative of the Rome Cultural Construction -- arena is the masterpiece of the original stone.
