The Cement Manufacturing Process
The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. …

Washed waste incineration bottom ash as a raw
While each clinker was manufactured with a consistent protocol, laboratory-scale clinker manufacture presents inherent difficulty in replicating identical conditions for each specimen. Thus, small operational variations during the manufacturing process likely influenced some of the observed differences in mineralogy.
