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]. In this paper we present a typicalWhat is a Grinding Aid? (with picture),10/02/2021· A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement.
