The Bogue composition is calculated from the oxide composition of the cement or clinker, based on the molecular weights of the oxides. 3-The CaO must be corrected for the amount which is combined with SO3 in CaSO4 and the uncombined free CaO. ∴ %CaOCombined = %CaO – SO3*56/80 – Free CaO. %CaOCombined = %CaO – SO3*0.7 – Free CaO.

The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.

Definition of Clinker. Clinker is a hard, black, or dark grey substance created when coal is burned. It's made of ash, soot, and minerals that fuse together at high temperatures. Clinkers can form on the fire grate, inside combustion chambers, or in flue pipes. These lumps can damage furnace components and reduce efficiency if not removed.
