Grinding Aids and Pack-Set Inhibitors DESCRIPTION MCH Customizedadditives are high-performance grinding aids generally used to increase mill production and to improve the cement quality. They are highly concentrated additives formulated with only selected raw materials, to guarantee absolute constancy of quality and superior performance.

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].
