What is the use of Calcium carbonate in the .

22.05.2009 · Well, cement is made with a mixture of CaO (lime) and SiO2, among other compounds. CaO is reduced from CaCO3 by thermal decomposition (calcination): CaCO3(s) + ∆H = CaO(s) + CO2(g) So CaCO3 is used to derive one of the major components of cement: CaO. As for iron, CaCO3 is used as a flux in the refining stages of "pig iron" into steel.
