When mixed with clay and heated to temperatures over 1,400°C, calcium carbonate in the limestone turns into calcium oxide, with the carbonate component released as carbon dioxide gas, and then reacts with silica in the clay to form a complex mixture of silicates in a product called cement clinker. This clinker then reacts with water to first ...

Limestone also forms when water containing calcium carbonates evaporates and deposits sediments on the sea floor. Over millions of years layers of sediment builds up, compresses and cements forming the rock. Limestone rock contains layers called strata, vertical joints and horizontal bedding planes.
