Analysis of Cement Superplasticizers and Grinding Aids A

2012-3-27  Grinding aids are common cement additives, and can consist of several different types of compounds such as alkanolamines, glycols or phenolic compounds. These are used to increase the throughput of cement clinker in the grinding mill. Generally, the concentration range of grinding aids added is from 50 to 500 ppm. After the grinding

Cement grinding aid and set retarder Westvaco

The grind was conducted using a 5,000 horsepower, 2-compartment mill in closed circuit with a Raymond Separator. The mill was started at 4:00 a.m. on a portland Type I clinker using REAX® G-2 as a "control" grinding aid in an amount of 0.016% based on the weight of the cement. Cement samples taken during the run were identified as follows:
