Belite cement

Belite cement

Belite cement is an example of a cement obtained with significantly reduced energy consumption than Portland cement (CEM I). It differs from Portland cement in a much slower hardening process, which is mainly due to the change in the amount of C3S in favor of C2S.

Ways to completely eliminate C3S are already known. They are cements with low energy consumption and not having a Portland clinker type structure. Depending on the ratio of all minerals to each other, one can also distinguish belite-pozzolan cements (C2S> 60%, a C3S i C3A = 0). Energy savings in the production of belite cements can be as high as 35%.
