Tricalcium Silie - an overview | ScienceDirect Topics
Tricalcium silie (Ca 3 SiO 5 or C 3 S) is the main phase of Portland cement clinker. It is called ‘alite’ in clinker because it is not pure tricalcium silie and contains a nuer of impurities substituted in its crystal lattice. Once in contact with water, Ca 3 SiO 5 is hydroxylated and the surface dissolves according to Eq. 5.1 (Barret et al., 1983; Barret and Bertrandie, 1986):
