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.
