About this document
Cement Grinding Aid Compositions by Nam Huynh is a document available to read on EtoBox.
The patent describes cement grinding aid compositions containing a water-soluble glycol and urea. The compositions improve grinding efficiency and reduce pack set tendencies of finished cement. Laboratory tests showed that compositions containing 40-70% glycol and 60-30% urea performed better than compositions using individual components alone at reducing pack set index and increasing specific surface area after grinding. The preferred composition contains 50% glycol and 50% urea.
