deg as cement grinding aid

  • Effects of Adding Boron Compounds to Glycol Based Grinding

    In other studies, DEG was used as a grinding aid with a dosage of 01%, which resulted in a lower 28 days compressive strength compared to reference cement [13] [14] These results were also seen in experiments using 100% DEG in this study The use of boron compounds led to an increase in the performance of DEG as a grinding aid
