  • The Manufacture of Portland Cement

    The Manufacture of Portland Cement

    The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 - Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3).
