Oct 26, 1971· Another addition to the product may be urea, which aids grinding efficiency. 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.
The first commercial use of grinding aids in the cement industry came about 40 years ago. These grinding aids are usually organic liquids, added in amounts usually not exceeding by weight. They are used to increase the product fineness at a given production rate or to increase the production rate at a given product sire.
