2020-11-3 Although the use of grinding aids can improve production and save energy, it is needless to say that the excessive addition of grinding aids will lead to more concentrated cement particles and increase the porosity of particles accumulation, which is unfavorable to the concrete structure and has caused the aversion of the concrete industry.

The results show that the fracture energy of mica in water is about half of what it is in air. Grinding aids are shown to reduce the fracture energy of mica, but not dramatically. Addition of grinding aids reduces the fracture energy by a further 10-20%, with tri-sodium citrate appearing to be the most effective.

2016-10-2 Grinding aids have been used successfully for dec-ades in cement production and many other areas, such as ceramics, pigments etc. The main effect is to reduce energy consumption and increase the grinding eciency. Additional features can be improved – e.g. powder flowability and strength development of binders. There is surprisingly lit-tle verified knowledge about the way in which the substances contained in grinding aids act effec-tively. There are correspondingly many hypotheses in the scientific literature as well as in industrial practice. Starting from basic physical and chemical background, the laboratory screening process cov-ering several hundred compounds and mixtures as well as extensive computer simulations (molecular modelling) [1, 2] provide a better understanding of grinding aids.
