The cement grinding aid has the advantages of uniformity and stability, no layering after long-term standing, low alkali content, no chloride ions, low doping amount only accounting for 0.01-0.03 percent of the cement amount, simple formula design, simplified production steps, good grinding aid effect and excellent reinforcement effect, can promote the energy-saving and emission-reduction effects of the cement industry and can completely meet market requirements.
