Tell me about Travertine
What is travertine?
How is travertine made?
The name travertine means something like a stone from Tivoli. This explanation makes it easy to see that the rock has its natural occurrence in the area around Tivoli in the Italian province of Lazio. Of course, this rock can also occur in Central Europe. The variety and quantity depending on the location and nature of the soil. The hot freshwater springs found in this region form an ideal breeding ground for the rock type travertine.
Through the so-called precipitation, to put it simply, the release of the source lime from these sources is the first step towards travertine. The rock itself consists almost exclusively of calcium carbonate and is referred to as freshwater lime due to this property and its natural occurrence in hot freshwater sources. The limestone can appear more or less porous, is lined with small voids and in most cases has a yellowish to brown basic color. Another typical limestone property is density. Like almost all other limestones, travertine is easy to saw up and break. The open pores and the good evaporation surface make this rock ideal for thermal facilities of all kinds. The material, therefore, has a slightly cooling and quick-drying effect.
Travertine is usually mined for days in limestone quarries or limestone mines. The top layer is loosened by means of blasting and the lower layers are removed in steps. Due to the local overlay of the limestone with other, load-bearing, layers of earth, mining is only possible under strict conditions.
Travertine is processed in the lime works. The first step is to shred the raw material again. Furthermore, in most cases, the boiling separates impurities from the actual raw material. Another method is to wash the rock. The resulting sewage water is transferred to a separate basin and reprocessed accordingly. After cleaning, the mixture is sorted into different sizes using an appropriate screening plant. Part of the material is ground directly or brought to the market as fertilizer limestone for agriculture. Another part of the rough stone is sold as grit or gravel and sand. The raw material remains unburned. Most of the limestone is processed in kilns to make so-called quicklime. In some cases, water is added to this quicklime. The resulting lime is known as hydrated lime and is also used in the construction industry.
The advantages Of Travertine
The advantages of travertine are clearly in its properties described above. Due to its large pore size, the water it absorbs can evaporate very quickly and therefore dries quickly and well. This peculiarity makes it particularly attractive for processing in the sanitary area. This rock was already processed in thermal institutions in the time of the ancient Romans. But travertine can also score outdoors. The naturalness harmonizes particularly well with other materials such as wood or glass. The only disadvantage is that travertine, like other limestones, is not very dirt-repellent. It, therefore, requires special care and cares when dealing with impurities. Since travertine is a purely natural material, it is also highly regarded in environmental terms. Its dismantling and processing place a hardly noteworthy burden on the environment and people. Since this is natural limestone, there is no risk of poisoning or other health problems for humans and animals.
