Publication Highlights

  1. The effect of mechanical activation (MA) in kaolin’s reactivity was evaluated.
  2. MA enhances the reactivity of kaolin
  3. Grinding time and rotation speed’s influence on kaolin’s reactivity was revealed.
  4. The MA of kaolin could lead to a higher amorphous content than in metakaolin.
  5. The results demonstrate that activated kaolin is suitable as cement precursor.
