Regarding the chemical composition of limestone, the ratio of calcium (calcite) and magnesium (dolomite) that is in the rock plays a very important role. In this regard, it should be mentioned that pure limestone theoretically would have more than 95% calcite in its composition and possibly 4% magnesium (dolomite).

Chemical Composition of Limestone. Limestone is made up of calcium carbonate, which has the chemical formula CaCO3. It is formed from the accumulation of marine life, such as shells and coral, that have been compressed over time. The calcium carbonate in limestone is what gives it its unique properties and makes it useful in various applications.

About Limestone. Limestone is very common in architecture, especially in Europe and North America. Limestone is extracted from quarries or mines. Part of the extracted stone, selected according to its chemical composition and optical granulometry, is calcinated at about 1,000 °C (1,830 °F) in different types of lime kilns to produce quicklime.
