Cement, primarily composed of limestone and clay, undergoes a series of chemical transformations during its creation. The primary raw materials are first quarried, then crushed and mixed in specific proportions to form what is known as 'raw meal.' This mixture, rich in calcium, silicon, aluminum, and iron, is heated in a kiln at temperatures exceeding 1,450°C. Here, a chemical reaction called calcination occurs, where limestone (CaCO3) decomposes into calcium oxide (CaO) and carbon dioxide (CO2).
