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). These are quarried and stored separately. The lime and silica provide the main strength of the cement, while ...

Cement clinker

Cement clinker

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilie materials such as clay during the cement kiln stage.
