Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar. 2  Pulverized limestone is used as a soil conditioner to neutralize acidic soils. 3  It is crushed for use as aggregate âthe solid base for many roads as well as in asphalt concrete.
Uses of limestone. Limestone, quicklime and slaked lime are all used to neutralise excess acidity-which may be caused by acid rain-in lakes and in soils. Limestone is used as a building material, and to purify iron in blast furnaces.It's also used in the manufacture of glass, and of cement (one of the components of concrete).he main uses of limestone and its products. 1  Limestone (CaCO 3) can be used as a building material and in the manufacturing of iron. 2  Glass-heated with sand and soda (sodium carbonate). 3  Cement-heated with clay in a kiln. 4  Concrete-mixed with sand, water and crushed rock. 5  Mortar-mixed with sand and water. 6  Quicklime-heated.
