Dec 04, 2008· CEMENT GRINDING AIDS. Dr J D Bapat. The cement grinding aids are the additional materials (gas, liquid or solid), admixed in small amounts during the cement grinding process (cement manufacture), which can significantly improve the grinding efficiency, reduce energy consumption, without compromising the performance of the cement.
The impact of grinding aids depends strongly on the fineness of the cement: The higher the surface area, the bigger the attraction force and therefore the bigger the benefit from an appropriate grinding aid. The optimum grinding aid is still, to a large extent, selected empirically.
