aceti acid as an ingredient of cement clinker grinding aid

cement milling process - walkingonwaterfl.org

The initial commercial versions of TDA were based on modified lignosulphonates and this began the modern grinding aid industry as well as leading to the development of water reducing admixtures. By the early 1960s amine acetates and acetic acid were also being used in grinding aids, and then glycols in the late 1960s and early 1970s.
