The main component of limestone is calcium carbonate, which can be directly processed into stone and burned into quicklime. Lime has quicklime and slaked lime. The main component of quicklime is CaO, which is generally in the form of a block, pure white, and pale gray or yellowish when it contains impurities. Quicklime absorbs moisture or adds water to become hydrated lime.

Slaked lime is also called slaked lime. Its main component is Ca(OH)2. The slaked lime is formulated into a lime slurry, a lime paste, a lime mortar, etc., and is used as a coating material and a tile adhesive. Limestone and lime are used in large quantities as building materials and are important raw materials for many industries.
