Limestone is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure.Sedimentary rock is important because it often contains fossils and gives clues about what type of rock was on the Earth long ago.he second way limestone is formed is when water containing particles of calcium carbonate evaporate, leaving behind the sediment deposit. The water pressure compacts the sediment, creating limestone. The area around the Great Lakes, such as Michigan, Indiana, and Illinois, has a large amount of limestone.
People have used calciumâs compounds for thousands of years â in cement, for example. Limestone [calcium carbonate] was called calx by the Romans. The Romans heated calx, driving off carbon dioxide to leave calcium oxide.To make cement, all you have to do is mix calcium oxide with water.The Romans built vast amphitheaters and aqueducts using calcium oxide cement to bond stones together. (1). Despite the long history of calciumâs compounds, the element itself was not discovered until electricity was available for use in experiments.alcium is used to remove oxygen, sulfur and carbon from alloys. Calcium from limestone is a vital component of Portland cement. Quicklime (CaO) is used in many applications in the chemical industry, such as treatment of drinking water â especially for water softening and arsenic removal, animal waste and wastewater.
