    2014-9-1 · 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 fineness.
