Hydration reaction is carried out in presence of 40%of tri calcium silicate, 30% of dicalcium silicate, 11% of tricalcium aluminate and 11% tricalcium alumino ferrite each.

These compounds are called, "Bogue's compounds".

Made a confusion because of C4AF. Tetra Calcium Alumino Ferrite.

Cement Compound - Chemical Formula

1) Tricalcium silicate - Ca3SiO5 or 3CaO.SiO2

2) Dicalcium silicate - Ca2SiO4 or 2CaO.SiO2

3) Tricalcium aluminate - Ca3Al2O6 or 3CaO .Al2O3

4) Tetracalcium aluminoferrite - Ca4Al2Fe2O10 or 4CaO.Al2O3.Fe2O3

What are Bogue's compounds? Please explain.

@Venu.

Bogues means water added so start with chemical process formation of chemical component is bogues. Above this material are composition material.

Priya said: (Aug 20, 2017)  
Bouges compounds are complex compounds, which is formed during clinkering stage.

Akash said: (Aug 27, 2017)  
Thank you all.

Govinda said: (May 9, 2019)  
These four Bogues compound are formed during chemical reaction of cement with water. Even type of cement is also decided by varying the percentage of these four bogues compound.
