Cement Chemistry - an overview ScienceDirect Topics

Ordinary portland cement contains, apart from minor CaSO 4 2H 2 O, four main crystalline phases: tri-calcium and bi-calcium silicates (in cement chemistry referred to as C 3 S and C 2 S, respectively), tri-calcium aluminate (C 3 A) and tetra-calcium alumino-ferrite (C 4 AF), in very strict ranges of proportions, each of them playing a specific role in cement manufacture and/or use.
