What is the formula of cement grinding aids?

Many friends consulted about the formula of cement grinding aids. Here, I want to tell you that the formula of cement grinding aids produced by different enterprises is different. The formula of cement grinding aids produced by different enterprises is also different from that of different products, liquid cement grinding aids and powder cement grinding aids.

What is cement grinding aid?

Cement grinding aids are chemical additives to improve grinding effect and performance, which can significantly increase the output of cement and various technical indicators. The molecule of cement grinding aids can form a protective film on the surface of cement particles, which makes cement particles not easy to wet, eliminates the static adsorption between cement particles, thus improving the fluidity of cement, reducing the cement caking index, improving the turnover efficiency, and reducing the loading and unloading time and pumping cost of cement. Especially conducive to water transport and port handling operations and long-distance road transport, can extend the time of cement inventory, reduce the troubles and costs caused by inventory clearance. It has been proved that the use of high-quality cement grinding aids can significantly improve the fluidity and dispersion of cement in the process of cement grinding. It is beneficial to increase the strength of concrete in the middle and late period.

What are the main raw materials of cement grinding aids?

The main raw materials of powder cement grinding aids are triethanolamine (grinding aids), industrial salt (leading to chloride ions exceeding the standard), mirabilite and sodium bicarbonate (easy to crystallize), which are produced by mixing and mixing fly ash as carrier.

The main raw materials of liquid cement grinding aids are triethanolamine, triisopropanolamine, ethylene glycol, sugar ether (toner or improve cement and workability/adjust setting time), sodium acetate, dodecylbenzene (increase flow rate), etc. After stirring uniformly in a fixed container, they are filled into barrels.
