  • Study on Material Properties of Magnesium Oxide Carbonized

    Magnesium carbonate can regenerate magnesium oxide after calcination and it means that the process is reversible and active magnesium oxide products have recyclability and recycling characteristics. More in-depth research on active magnesium oxide cement is led by Dr. Al-Tabbaa Ph.D. University of Cambridge UK.
