Limestone (principally calcium carbonate) is a naturally occurring mineral and is found widely throughout the world. It is mainly used for road construction, in the production of concrete and as a structural fill. It is also the principal raw material for the production of cement, quicklime, and numerous other products. Quicklime (principally calcium oxide) is produced by the thermal decomposition of limestone at temperatures above 900°C. About half of the quicklime made is reacted with water to produce calcium hydroxide (in the form of milk or lime putty). Lime products are generally the most readily available and most cost-effective alkaline chemicals and are used in a wide variety of industrial processes. In many countries, the largest use is for the production of iron and steel, followed by building and construction, environmental protection, and the chemical industry. Hydraulic lime is a traditional product used in building, especially as a binder in mortars. The main environmental issues associated with the production of lime and limestone products are emissions to air and energy consumption.
