low cost cement grinding aid patent

Influence of glycerin grinding aid on the compatibility between cement ...

Low surface energy is effective to crushing cement particles, which makes the cohesion difficult during grinding. However, the decrease of adhesive work could reduce the adsorption of chemical admixtures on the surface of cement particles. Additionally, the degree of the effect increases with the increase of GL dosage. 3.2.
