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.

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.

Milling aids have been predominantly developed to increase the performance or grinding capacity of cement products, and alcohol amines have been used as grinding aids in cement grinding processes for many years. Moreover, the setting point of cement produced with grinding aids is most often changed. In this study, the effects of alkanolamines and boron compounds in different mixing amounts as grinding aids on the set point of cement were researched. Triethanolamine (TEA) and triisopropanolamine (TIPA) were used as alkanolamines and boric acid (BA) and anhydrous borax (AHB) as the boron compounds. It is evident that BA with TEA had a small effect on the cement setting point where the former decreased the retarding effect of the latter, but BA had no effect with TIPA. AHB decreased the retarding effect of TEA but had no effect with TIPA on setting times. When the boron compounds were added to TEA, they accelerated the initial setting points of cement by 15 to 20 minutes and the final setting points by 25 to 30 minutes according to the amount of TEA used.

A kind of composite grinding aids was developed of expanded perlite and grinding aids M-1,and the effect of grinding on it was analyzed by cement powder fineness, specific surface area, laser particle size analysis, SEM image and cement mortar strength performance test. The composite grinding aids have outstanding grinding effect, which shield surplus electric charge, prevent the agglutination between particles, increase the standard water consumption, and decrease the condensation time. Furthermore, the influence of cement properties were tested, and results indicate that the total testing standards meet JC/T667-2004 of grinding aids.

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.
