Grinding aids for high performance cements - C-ADD Mapei
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.
