  • Calcined dolomite CALCINOR

    Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings. Calcium and magnesium oxide or calcined dolomite are obtained from dolomitic minerals such as calcium carbonate and magnesium (Ca Mg (CO3) 2, through the calcination process.

  • Understanding the hydration of dolomite in cementitious

    This study investigates the hydration of dolomite, CaMg(CO 3) 2, with calcined clay in presence of calcium hydroxide and ordinary Portland cement.The hydration products as well as the microstructure at various ages were characterized using X-ray diffraction (XRD), thermogravimetric analysis (TGA), and mercury intrusion porosimetry (MIP).
