[0002] Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It can significantly increase the hourly output of cement, the strength of cement at all ages, and improve its fluidity. Cement grinding aid can greatly reduce the electrostatic adsorption and balling phenomenon formed during the grinding process, and can reduce the re-agglomeration tendency of ultrafine particles formed during the grinding process. Cement grinding aid can also significantly improve cement fluidity, improve the grinding effect of the mill and the powder selection efficiency of the powder classifier, thereby reducing grinding energy consumption. Cement produced using grinding aids has a lower compaction and agglomeration tendency, which is beneficial to the loading and unloading of cement and can reduce the wall hanging phenomenon of cement storage. As a chemical additive, grinding aid can improve the distribution of cement particles and stimulate hydration dynamics, thereby improving the early and later strength of cement.
