Multifunctional cement grinding aid

Abstract

A multifunctional grinding aid for cement is prepared from powdered coal ash, sodium chloride, triethanolamine, sodium silicate, zinc ore powder, benzyl trisodium, gypsum, and biethanediol. It can speed up grinding, and improving the strength and anti-radiation, antistatic, anticorrosion, antifreezing and antirust functions of cement.

Description

technical field

[0001] The invention belongs to the technical field of cement grinding, and in particular relates to a multifunctional cement grinding aid which is rust-proof, convenient for construction in winter, reduces the radiation of building materials to the human body and improves cement performance. Background technique

[0002] Cement grinding aids can reduce cement production costs, increase cement production efficiency, increase cement output, improve cement performance and quality, and improve the operational performance of cement production processes. It has been widely used in countries all over the world. my country is a big cement producing country in the world, and the research and development of cement grinding aids is very fast. With the continuous deepening of application research, cement grinding aids not only consider the grinding aid effect of traditional grinding aids, but also increase the output of cement mills while maintaining the same fineness,...
