Another way cement manufacturers reduce the amount of clinker in their cements is with interground limestone. That is, they add raw limestone into the cement mill so that the clinker and limestone grind together. The limestone itself does not hydrate, but its fine particles help to accelerate the hydration reactions of the portland cement clinker.
