The organic formation of limestone occurs from the accumulation of decayed coral, shell, algae and fecal. The chemical formation of limestone occurs from the precipitation of calcium carbonate from lake and ocean water. Modern construction uses calcite in the form of limestone and marble to produce cement and concrete. These materials are easily mixed, transported, and placed in the form of a slurry that will harden into a durable construction material. Concrete is used to make buildings, highways, bridges, walls, and many other structures.

Limestone is a sedimentary rock that is composed primarily of calcite (calcium carbonate, CaCO 3) and dolomite (calcium magnesium carbonate, CaMg (CO 3) 2 ).
