Limestone

Limestone is a common, chemical sedimentary rock formed primarily from calcium carbonate. It is generally light-colored and can also include fossils of calcium carbonate-containing organisms, like corals. Limestone can be found all over the world and is the major type of rock found in karst features (crystal cave systems found in bedrock. Limestone It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar. Pulverized limestone is used as a soil conditioner to neutralize acidic soils (agricultural lime). Is overwhelmed to be used as aggregate—the strong base for many roads as well as in asphalt concrete. Geological formations of limestone are most of the great petroleum reservoirs; As a reagent in flue-gasoline desulfurization, it reacts with sulfur dioxide for air pollution manipulate.
