The Theoretical Research on Development Direction of Cement Grinding Aids

Abstract

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.
