Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This paper seeks to assess the effect of such additions on variations in flow of cement pastes, including static yield stress (τ 0) and viscosity (η).Grinding tests were performed at fixed specific energy consumption (Ec) or Blaine cement …

Read OnGrinding 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].
