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 … See more The Portland clinker essentially consists of four minerals: two calcium silicates, alite (Ca3Si) and belite (Ca2Si), along with tricalcium aluminate (Ca3Al) and calcium aluminoferrite (Ca4AlFe) (Ca3Si), Ca2Si, Ca3Al, Ca4AlFe … See more Portland cement clinker (abbreviated k in the European norms) is ground to a fine powder and used as the binder in many cement products.
