Limestone, sand and gravel are used for building and public works projects.  These materials are key ingredients in cement, concrete and asphalt for construction of roads, buildings, and bridges.

Specialty uses of limestone include the manufacturing of pharmaceuticals, toothpaste, paint, paper, caulking, and glass. Flooring materials, carpet and plastics all contain finely ground recycled limestone. Common antacids are virtually 100% finely ground limestone. Farmers can reuse limestone to neutralize acidity in their soils, saving money by reducing fertilizer use while improving crop yields.
