Travertine
Travertine is a bituminous lime made of calcium carbonate that is chemically deposited around springs and drains, along rivers, and rarely in lakes. The main constituent minerals of limestone are calcite and aragonite, and the lemon and yellow and red colors of limestone are due to the presence of iron oxide in the chemical composition of limestone. These rocks have low to medium crystal porosity and sometimes form in an aquatic environment with a high porosity of the mould.
Travertine deposition occurs due to the exchange of carbon dioxide gas with a groundwater source, which causes severe saturation of calcium carbonate and is accompanied by the growth of nuclei or crystals in an almost neutral medium.
Limestone usually forms on steep slopes and the layers within the rock are undulating and have a slope. In situ travertines are rarely horizontally layered. Layering in the range of millimeters to thirty centimeters is very common in this rock and is the result of daily and seasonal growth regimes.
The characteristics of travertine stone are color versatility, light weight, excellent sand resistance, good compressive strength, stable color, tooling ability, and good adhesion to mortar.
Travertine uses: exterior facade stone, interior facade stone, landscaping and antique stone
