Travertine is named for its many holes on the surface of stone. Its scientific name is tuff or travertine. Commercially, it is classified as marble. The use of the stone by humans is very old, and the building that best represents the Roman culture - the gladiator is the masterpiece of the original stone.
The color of the travertine is mostly beige, which makes people feel gentle, rich in texture and clear in stripes. The decorative buildings often have strong cultural and historical charm and are used by many buildings in the world. Designed by American Pei Ming Architects, the interior and exterior decoration of the Bank of China Building at Xidan Road, Beijing, chose the Italian Roman travertine, which shared 20,000 square meters. Why not call it marble, because its texture and appearance are completely different from the marble in the traditional sense, and the decorative boundary is customary.
Its formation is generally considered to be a calcium material precipitated from carbonated spring water (usually a hot spring) under atmospheric conditions. The specific formation is that the circulating groundwater containing oxidized carbon carries a large amount of calcium carbonate in the solution of the plant. When the groundwater reaches the surface of the spring, some carbon dioxide is released and condensed in the sediment layer of the calcium carbonate to form A rare bubble (hole), which has a travertine. Unlike limestone sediments in the ocean, most of the tuffs are deposited quickly in rivers or lakes and ponds. This rapid deposition prevents the release of organic matter and gases, resulting in beautiful textures, but it is also disadvantageous. The delamination of the internal crack is created, causing it to weaken in intensity consistent with the direction of the texture.
Because there are holes in the tuff, its unit density is not large, it is suitable for covering materials, and it is not suitable for the structural materials and basic materials of the building. In the past, people used a lot of travertine as the basic material and structural material of the building, but after using concrete, it is not used much now. In addition to yellow, travertine has green, white, purple, pink, brown and so on. There are also travertine discoveries and outputs in Henan, China.
Travertine is mainly used in architectural exterior decoration and interior flooring and wall decoration.
