Research Situation

It can increase the cement fineness, improve cement production and improve comprehensive performance of cement significantly by adding grinding aids, and promote the use of grinding aids in reducing the energy consumption of cement production, with the adjustment of national economic growth and the elimination of backward production capacity. But the effect mechanism of the grinding aids is divided, and the grinding effect of the system is still need to be improved. In this paper, the development history of cement grinding aids is introduced, and the grinding aids are summarized systematically from the aspects of the grinding mechanism and present research situation at home and abroad. Study shows that current research only stay on the level of practice, not related to the in-depth research on the theory system and theoretical model, a set of grinding efficiency of composite grinding system and the corresponding scientific theory are need to establish.

Grinding aids to increase grinding efficiency in cement production are materials that can produce large amounts of high-quality cement in a short time by reducing surface energy by preventing particle agglomeration and improving fluidity. In the paper, a grinding aid using glycerol-waste antifreeze(GAP) is prepared and its effect on the grinding properties of clinker is investigated in contrast to that without the grinding aid. The results are as follows: The angle of repose of the cement powder added with GAP decreases as the grinding time increases (decreases by 3.8° when the grinding time is 60 minutes), indicating that it increases the flowability of the powder. On the contrary, the residual amount of 45µm sieve is also significantly reduced (4.6% decrease) and the specific surface area increases (30.5m2/kg), which results in an increase in the grinding efficiency. In the size range of 3 to 32µm, it increases the particle content, makes the particle size distribution uniform, the 7d and 28d activity index of the powder is improved by 5% and 6%, respectively, and increases the compressive strength of the cement. In addition, it is confirmed that the performance of the TEA grinding aid and the grinding aid are similar, and are very effective in terms of economy.

Cement grinding aids has been widely used in cement grinding process. The development of traditional compound cement grinding aids, such as triethanolamine and salts based has encountered a bottleneck. Synthesis of cement grinding aids can be improved by the molecular structure design of traditional cement grinding aids, or even lay aside the shackles of traditional cement additive and synthesize high-grinding effect, high performance and low cost cement grinding aids. In this paper, it has proposed two types of cement additives research direction，medium-small molecule and polymer synthesis system. Finally, it had introduced the application performance advantages of two new synthetic grinding aids, compared to triethanolamine and triisopropanolamine.
