Travertine is named because there are many holes on the surface of the stone. The scientific name of the stone is tuff or travertine. Commercially, it is classified as marble. Humans have used this stone for a long time, and the most representative building of Roman culture-the arena is the original masterpiece of travertine.
The color of travertine is mostly beige, which makes people feel gentle, rich in texture, and clear in stripes, which promotes the decoration of buildings to have a strong cultural and historical flavor, and they are used by many buildings in the world. The interior and exterior decoration of the Bank of China Building at the intersection of Xidan Road, Beijing, designed by the American firm I.M. Pei, chose Rome Travertine from Italy, sharing a total area of 20,000 square meters. Why not call it marble? Because its texture and appearance are completely different from marble in the traditional sense, and the decoration industry is simply customary. Its formation is generally considered to be a calcareous material precipitated from carbonate-containing spring water (usually hot springs) under atmospheric conditions. The specific formation is that the circulating groundwater containing carbon dioxide takes away a large amount of calcium carbonate in the solution. When the local sewage reaches the surface of the spring water, some carbon dioxide is released and condensed in the sedimentary layer of calcium carbonate, forming a rare occurrence. Air bubbles (holes), and thus have travertine. Unlike limestone precipitation in the ocean, tuff is mostly deposited rapidly in rivers, lakes, and ponds. This rapid deposition prevents organic matter and gas from being released, resulting in beautiful textures, but the disadvantage is that it also Delamination of internal cracks will occur, weakening its strength in line with the grain direction. Because tuff has holes, its unit density is not high, so it is suitable for covering materials, but not suitable for structural materials and basic materials of buildings. People have used travertine as the basic and structural materials for buildings in large quantities, but with concrete, it is not used much. In addition to yellow travertine, there are many kinds of green, white, purple, pink, brown and so on. Travertine is also discovered and produced in Henan, my country.
Travertine is mainly used in building exterior wall decoration and indoor floor and wall decoration.
