Portland cements: Clinker, gypsum and limestone---but with about 10% additional limestone. • Portland-limestone cements have been used under the ASTM C1157 Performance Specification for the last 20 years • Portland-Limestone cements were added to CSA A3001 in 2008, with up to 15% intergroundlimestone replacing cement clinker and to ASTM C595

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.

and alumina. 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.
