    The most common type of cement used today is Ordinary Portland Cement (OPC). Its composition is as follows:

    1. Calcium Oxide (CaO) – 61-63%
    2. Silicon dioxide (SiO2) – 17-25%
    3. Aluminium Oxide (Al2O3) – 4-8%
    4. Sulphate – 1.5-4.5%
    5. Sulphur trioxide (SO3) – 1-3%
    6. Ferric Oxide (Fe2O3) – 0.5-0.6%
    6. Traces of other substances like MgO, Cl, K2O etc.
