Lime is produced by calcination of sedimentary rocks, the main component of which is calcium carbonate and perhaps magnesium oxide, When the content of magnesium oxide more than 7% of lime is called magnesia, with a smaller it presence of calcium. In the construction using both lime. These rocks are tight, clean and dolomitized limestone, chalk, shell limestone and other Rocks should not contain more than 8% clay impurities (the fewer the better and cleaner lime). Roasting is performed at a temperature of 900° — 1200°C up to possible the complete removal of carbon dioxide, that is, the decomposition of calcium carbonate with the release of carbon dioxide and formation of calcium oxide or so-called lime-quicklime.
