grinding calcium clinker

Comprehensive understanding of grinding aids

the industrial grinding of cement, even without the use of grinding aids. Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy - droxylated. This is also important because it as-sists the grinding, in other words water is a weak grinding aid. The chemical reaction of oxide ions

Portland Cement Clinker - an overview | ScienceDirect Topics

Portland cement is a fine powder produced by grinding Portland cement clinker (more than 90%), a limited amount of gypsum (calcium sulphate dehydrate – CaSO4.2H2O, which controls the set time) and other minor constituents which can be used to vary the properties of the final cement. The standard Portland cement is often referred to as Ordinary Portland Cement, and European Standard EN197-1 gives the following description:
