Grinding aids for high performance cements
2018-3-29 Grinding aids for high performance cements Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].

Determination of grinding aids in portland cement
1998-9-1 Introduction. Energy utilization during the grinding process of Portland cement clinker and gypsum can be significantly improved by adding polar organic compounds (referred to as grinding aids) in concentrations less than 500 ppm .Because of their highly polar nature, grinding aid compounds preferentially adsorb on surfaces formed by the fracture of electrovalent bonds (i.e., Ca-O and Si-O).
