• Analysis of Cement Superplasticizers and Grinding Aids A

    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
