Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. Setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic
522 The chemical composition of Portland cement involves both major and minor oxides [ 5 ]. The major oxides include CaO, SiO 2, Al 2 O 3, and Fe 2 O 3 whereas the minor oxides also include MgO, SO 3, and some alkali oxides (K 2 O and Na 2 O) and sometimes the inclusion of other compounds, P 2 O 5, Cl, TiO 2, MnO 3, and so forth [ 5 ].
However, cement contains water (H 2 O), sulphate (SO 3 ), sodium oxide (Na 2 O), potassium oxide (K 2 O), gypsum (CaSO 4 ·2H 2 O), which are denoted as H, S, N, K, and CSH 2, respectively. Note that gypsum (calcium sulphate dihydrate) is considered as CaO·SO 3 ·2H 2 O and hence its notation is CSH 2.
