Travertine is a porous marine sedimentary rock. Limestone has undergone re-accumulation over thousands of years. The main environment for its formation is on the ocean floor. This unique natural material comes from the extraordinary craftsmanship of nature. Since its main component is calcium carbonate or magnesium carbonate, which is easily dissolved and corroded by water, many natural irregular pores appear in these sediments.
1. Travertine Color
The color of travertine is mostly beige, mainly gray, beige, beige, yellow, gold, gray, brown, coffee, light red, maroon and other colors.
The main producing areas are Italy, Turkey and Iran. Travertine is also found and produced in Henan, China.
2. The advantages of travertine
A. Travertine has uniform lithology, low hardness, easy mining and processing, light density, and easy transportation;
B. Travertine has good processability, sound insulation and heat insulation;
C. Travertine has fine texture, small hardness, easy to carve, suitable for carving materials and special-shaped materials;
D. Travertine is rich in color, unique in texture, has a special hole structure, and is very decorative.
3. Disadvantages of Travertine
A. lack of strength
Due to the existence of a large number of pores, the bulk density is low, the water absorption rate increases, and the strength decreases.
B. fracture
The biggest safety problem of travertine is some muddy lines and muddy belts, which are the weakest links in flexural strength. The back of the beautiful pattern is often the place with the lowest strength and the most prone to breakage.
C. Pollution
Due to the characteristics of many holes in travertine, when travertine is used as exterior wall decoration material and indoor floor material, various pollutants can easily penetrate into the stone through the holes, causing the stone to be polluted.
D. burst
Due to the large number of pores in travertine, the water absorption rate increases, the strength decreases, and the weather resistance deteriorates. In places with large temperature differences, the water and gas reservoirs in the cave will freeze and expand. If the temperature is too low, it will cause serious cracking and cracking of the stone, posing a safety hazard.
