Jun 19, 2020· A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.
Another addition to the product may be urea, which aids grinding efl'rciency. The urea when used in amounts up to about 5 percent of the sulfonated lignin material also increases the compressive strengths of cement. However, urea may be used in larger amounts with other additives without any deleterious effects on strength and set time.
