  • Main Components of Portland Cement Clinker

    Portland cement is attained by grinding clinker with few amounts of a few other minerals; thus, its structure does not depart far from that of clinker. Although the other potential ingredients may be inexpensive natural materials, clinker is made in a kiln which is an energy-intensive chemical procedure.

  • Cement clinker

    Portland cement clinker (abbreviated k in the European norms) is ground to a fine powder and used as the binder in many cement products. A little gypsum (less than 5 wt.%) must be added to avoid the flash setting of the tricalcium aluminate (Ca 3 Al 2 O 6 ), the most reactive mineral phase (exothermic hydration reaction) in Portland clinker.

    Portland Cement is obtained by grinding Clinker with only minor amounts of a few other minerals, so its composition does not depart far from that of Clinker. Other Cements (i.e. non-Portland Cements , for example pozzolanic Cements , blast furnace slag Cements , limestone Cements and masonry Cements ) contain larger amounts of other minerals and have a much wider composition range.

  • Cement Clinker

    Portland cement is produced by sintering (fusing together without melting to the point of liquefaction) limestone, sand, and aluminosilicate materials such as Kaolin clay to produce cement clinker. Clinker is then ground with additives, such as limestone and gypsum, to form Portland cement. Kaolin clays can be used as a source of alumina.

    The recovered cement paste contains all the main clinker minerals similarly to the initial cement. The results provide evidence for the possibility of recycling hydrated cement and concrete into the cement clinker. The recycled clinker will potentially have a lower carbon footprint in comparison to original Portland cement.
