Effect of clinker grinding aids on flow of cement-based
· Typical GA dosage rates used during grinding of clinker vary from 0.01 to 0.15 of the manufactured cement mass. After the grinding process GAs may not preserve their original molecule structures however they do remain adsorbed onto the cement particles to entail variations of cement properties whether in the fresh or hardened states.

Difference between Clinker and CementCivil Engineering
· Clinker is produced inside the kiln during the cement manufacturing process. Raw mix is heated and then rapidly cooled to produce the marble-sized pellets of clinker. Read Clinker Manufacturing Process. Cement is produced by grinding clinker (added with different active ingredients to achieve the desired properties of cement) into a fine powder. 4

· The project is looked at grinding limestone separately as opposed to grinding it with clinker and gypsum which it currently does. The plant is using a mill it only uses occasionally to grind the limestone to the desired size. A full-scale trial was run in the autumn of 2018. Products from the trial are now being tested at a laboratory.
