Travertine is a kind of calcium carbonate with a compact strip structure that is created through water currents, especially the waterfalls and as well, hot and cold springs. Due to the chemical composition of calcite, the calcium carbonate in places with high values of evaporation leaves supersaturated solutions. Tufa is a porous travertine that could be found near waterfalls. Coquina is also a type of calcium carbonate rock with a weak structure; it is composed of shells and corals fragments.

The Calcium carbonate is especially used in architecture, and many historical masterpieces all around the world, especially in North America and Europe are made from this combination. Many buildings in Kingston, Ontario of Canada are made of calcium carbonate, so they are also called calcareous cities. Among the most important artworks of the world, the Abraham Lincoln Statue in Washington, the Parthenon Building in Athens, the Church ceiling of Kraków in Poland, and the Great Lion Statue of London’s Trafalgar Square are made of the calcium carbonate. Another feature of the calcium carbonate is that it could be easily crushed into smaller pieces. Meanwhile, its durability is long-lasting and could be well exposed on the surface. The application of the calcium carbonate in buildings was common in the early
