Travertine

Classification：Sedimentary Rock

A limestone formed by chemical precipitation. Karst in the cave stalactites and stalagmites are travertine. Calcite veins can also be formed by travertine.

Travertine, also known as Kong Shi, belongs to limestone and marble. Usually it is cream or light red, which is made up of calcite from hot spring. Because the water flows out of the waste lime residue pile, it dissolves calcium in the lime slag and accumulating again. There are many holes in these deposits, which can store and absorb water. These small holes need to be filled with synthetic resins or cement, otherwise a lot of maintenance work will be needed.

Travertine, called Travertine (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. Most of them are formed in limestone terrain rich in calcium carbonate. They are formed by dissolution of calcium, calcium carbonate and other minerals dissolved in water in river bed, lake bottom and other places. Because of the pore in the process of heavy accumulation, and because its own main component is calcium carbonate, it is easy to be dissolved and corroded by water, so many natural irregular holes will appear in these deposits.
Because of the unique formation process of natural rock, it is also a little confused in the division, some make it to marble, because it is formed of limestone, and some still regard it as limestone, after all, he did not undergo the process of metamorphism.
Natural limestone is formed because of limestone, so its color is similar to limestone, but because of different forming conditions, the Travertine will be more colorful than limestone and brighter in color. Usually the cave stone is mainly gray, rice white, rice yellow, yellow, golden yellow, brown, coffee, light red, brown red and other kinds of color, a few green, but the mineral layer is too thin, no mining.

Components:
Travertine, made of calcium carbonate, can make bonsai and rockery.

The cause of formation:
The ancient people burnt lime, the waste residue partly dropped and accumulated, and the accumulation of ground water passed, the time was long, the spring water outflows from the waste lime slag heap, dissolved calcium in the lime slag and accumulated, and there are many holes in these deposits. These holes can be stored and absorbed. Travertine is small in hardness, light in weight and easy to engrave. It is a good material for bonsai and rockery. It is more beautiful than coral reef and can be planted on Travertine for ornamental. The proportion of Travertine is smaller than the stalactite.
Travertine (Kong Shi): limestone and marble. Usually it is cream or light red, which is made up of calcite from hot spring. Because the water flows out of the waste lime residue pile, it dissolves calcium in the lime slag and accumulating again. There are many holes in these deposits, which can store and absorb water. These small holes are usually filled with synthetic resins or cement, otherwise a lot of maintenance work is needed. The Cambrian dolomitic limestone and dolomite are widely distributed in Kaili area, but in engineering investigation, it is found that there is a --Travertine in the strata of the lower shales of the lower Cambrian system, which is similar to dolomitic limestone. The analysis and study of the engineering characteristics and causes of Travertine is of great significance to the construction of the process.

Travertine (Travertine) features:
1. cave stone is homogeneous in lithology, small in soft texture, very easy to be mined, light in density (density) and easy to transport. It is a widely used building stone.
2. stone has good workability, sound insulation and heat insulation, can be used for deep processing, building decoration materials is excellent.
3. travertine fine texture, high processing adaptability, low hardness, easy carving, suitable for carving wood and shaped timber.
4. cavern is rich in color, unique in texture, and with a special hole structure. It has good decorative properties. At the same time, because of the natural hole characteristics and beautiful texture of the cavern, it is also a good material for potted and rockery.

Travertine disadvantages:
The disadvantages of Travertine seem to be more, but for some people, those may not be important, because Travertine has many styles to choose from. To measure the advantages and disadvantages of Travertine, consumers with specific needs need to think about it.
One of the disadvantages is that the Travertine ceramic tile will suffer corrosion when it meets acid liquid. It may not be a problem for home. But if the acid liquid is spilled, tile may need to replace.
Another disadvantage is that Travertine itself has many pores. These pores may be very small or quite large. Most of Travertine is composed of macropores and small pores. These pores will normally be filled in ceramic tile factories, so as to keep the surface smooth.
With the passage of time, often wear will lead to loose filling material or wear out. In such a case, these pores will revive. Regular nursing for Travertine may include surface pores. Accordingly, we need to consider that the owners need to spend a lot of time to keep the tiles in the best condition.
Filling pores is not easy. The color of filler materials should match with the color of tiles. Any type of mud or epoxy is suitable for filling pores, but in order to restore the original appearance, the filling color should be as close as possible.
Finding matching color and filling holes do not need to take any special skills, and the cost is not expensive. But one thing, that is time consuming. The filling material must be uniform and neat, and any residual material must be cleaned up.
For many people, the advantages and disadvantages of Travertine are decisive factors. However, for those rooms with small flow volume, these pores need not be considered at all.
