Conclusion: (1) Triethanolamine, triisopropanolamine and diethanol monoisopropanolamine are all good cement grinding aids, which have good grinding effect. (2) Triethanolamine has excellent early strength improvement, but can not even weaken the late strength of cement; triisopropanolamine can not promote the early strength of cement, but can improve the characteristics of late strength; diethanol monoisopropanolamine It has the advantages of both, and has obvious improvement on early strength and late strength. (3) Due to the prevalence of chloride salt early strength agents and triisopropanolamine compared with triethanolamine, there are many advantages in terms of dispersibility, age enhancement, application conditions and relative costs, so the application is gradually increasing. , an increasingly widespread replacement of triethanolamine.

Cement is a very basic material in the construction industry and plays a very important role in the development of the national economy. However, in the cement production process, the energy consumption is high and the utilization rate is low, mainly due to the accumulation of fine powder particles during the grinding process, which causes the paste ball and the adhesive liner to reduce the grinding efficiency, so that about 80% to 90 % of the energy is consumed in the form of heat. In order to improve this situation, it is common in the industry to add a small amount of grinding aid to the grinding material to improve the grinding effect. Rate and reduce the energy consumption of grinding.

In the field of cement grinding aids, the early alcohol amine compounds used in cement grinding aids are mainly triethanolamine due to triisopropanolamine. The dispersibility and late strength are superior to triethanolamine, and its market share is expanding. Compared with triethanolamine, triisopropanolamine The divergence, the enhancement of each age, and the application conditions have the following advantages
