CEMENT RAW MATERIALS - International Cement Review

Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise ...

Better and cheaper cement: Optimising raw material properties

2021-06-24  Cement performance is intially set by targeting a clinker lime saturation factor (LSF). This gives the required product strength but also provides good clinker burnability and reasonable economy of operation. The LSF level is often around 95 or 96, although the optimum LSF will vary depending on the raw material properties and other factors.
