Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.

Limestone can be directly processed into stone using crushing equipment and fired into quicklime. Quicklime absorbs moisture or adds water to become hydrated lime. The main component of hydrated lime is calcium hydroxide. The hydrated lime is prepared into lime slurry, lime paste, etc., as coating materials and brick adhesives.
