What is Limestone?
Limestone is a sedimentary rock composed of the mineral calcite (calcium carbonate) . The primary source of this calcite is usually marine organisms. Limestone makes up approximately 10 percent of the total volume of all sedimentary rocks.
Pure limestones are white or almost white. Because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colors, especially on weathered surfaces.Limestone may be crystalline, clastic, granular, or dense, depending on the method of formation.
Uses of limestone
Limestone is quarried for roadbeds, building and landscape construction, and cement manufacture. Limestone is especially popular in architecture, and many landmarks around the world, especially in North America and Europe , are made primarily of the material. Limestone is readily available and relatively easy to cut into blocks or more elaborate carving. It is also long-lasting and stands up well to exposure. However, it is a very heavy material, making it impractical for tall buildings; it is also quite expensive. Most limestone used in construction comes from India .
