  • It is crushed for use as aggregate—the solid base for many roads as well as in asphalt concrete.
  • Geological formations of limestone are among the best petroleum reservoirs;As a reagent in flue-gas desulfurization, it reacts with sulfur dioxide for air pollution control.

  • It is added to toothpaste, paper, plastics, paint, tiles, and other materials as both white pigment and a cheap filler.
  • It can suppress methane explosions in underground coal mines.
  • Purified, it is added to bread and cereals as a source of calcium.
  • Calcium levels in livestock feed are supplemented with it, such as for poultry (when ground up).
  • It can be used for remineralizing and increasing the alkalinity of purified water to prevent pipe corrosion and to restore essential nutrient levels.
  • Used in blast furnaces, limestone binds with silica and other impurities to remove them from the iron.
  • It is often found in medicines and cosmetics.
  • It is used in sculptures because of its suitability for carving
