Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a truly versatile commodity. Portland cement is essential to the building industry, but despite our Nation's abundance of limestone, there have been cement shortages in recent years.

Limestone is most commonly employed as rough block for building and construction. Additionally, it is used as dressed stone in various applications including curbing, paneling, veneer, and tile (Dolley 2007). Two general phases of limestone production exist: quarrying and processing. Each of these phases is described below.
