This is because calcium oxide has many uses, is inexpensive and is easy to create. At the Carmeuse’s Beachville plant, high purity calcium quicklime and dolomitic quicklime are produced primarily for the steel-making industry. Hydraulic lime is also called as water lime. It can also be used in plastering works and in cement as a binder. It is used in the refining of sugar and as a disinfectant and germicide. Lost your password? The chemical equation is as follows: This calcium hydroxide quickly reacts with carbon dioxide to form a mortar. However, hydrated high calcium lime Ca(OH)2, monohydrated dolomitic lime Ca(OH)2.MgO, calcitic quicklime CaO, and dolomitic quicklime CaO.MgO are most frequently used. Before the invention of the electric bulb, limelight was used to illuminate theatrical productions. It is also known as caustic lime. It is used in steelmaking to help separate impurities from the molten steel. This is also called as white lime or rich lime or high calcium lime or pure lime.
