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 (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
An appropriate mix of gypsum and anhydrite is necessary because the CaSO 4 ⋅2H 2 O will dehydrate to some extent in the heat of the cement mill to form hemi-hydrate, also known as plaster of Paris. This will cause a false (plaster) set if present in excessive amounts, but a small amount enhances the solution of SO 3 which is necessary to ...
