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 (O2–) with water (H 2 O) to form hydroxide,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].
