alleryStart learning →Tetracalcium aluminoferrite, in Bogue's compound notation, is written as:
A4 CaO . Al2O3 . Fe2O3 (C4AF)
B2 CaO . SiO2 (C2S abbr.)
C3 CaO . Al2O3 (C3A abbr.)
D3 CaO . SiO2 (C3S abbr.)
Answer & Solution
Correct answer: A. 4 CaO . Al2O3 . Fe2O3 (C4AF)
1. Table 1.2 in §1.4 names Tetracalcium Aluminoferrite as 4CaO.Al2O3.Fe2O3, abbreviated as C4AF.
2. The other three formulas correspond to C3S, C2S and C3A respectively.
