Frequently Asked Questions
In the context of Portland cement chemistry, yes. 'Belite' is the industrial and technical name for the impure dicalcium silicate found in cement clinker.
Tricalcium silicate hydrates rapidly, providing early strength. Dicalcium silicate hydrates slowly, contributing significantly to the strength increase over months and years.
Yes, but it is rare. The mineral form of one polymorph (γ-Ca₂SiO₄) is known as larnite.
In scientific English, it is pronounced /ˈsɪlɪkeɪt/ (SY-li-kate), not /ˈsɪlɪkət/. Mispronunciation can mark a speaker as unfamiliar with technical terminology.
