Investigation of the Change in the Phase Composition, Properties, and Hydraulic Activity During the Thermal Treatment of Magnesian Materials

  • Published:
Refractories and Industrial Ceramics Aims and scope

The effect of the heat treatment regime on the hydraulic activity of magnesian materials was determined from the heat release during interaction with water. Hydration processes proceed efficiently, hardening structures are formed after calcination of the initial magnesian materials in the range of 500 – 800°C. Therefore, in the production of hydraulically active magnesium oxide used to make the magnesian binder, it is necessary to bake magnesian materials regardless of their nature at low or moderate temperatures in the range of 500 – 800°C. The change in the structure and properties of magnesian materials during heat treatment has a great influence on the processes of sintering refractory materials.
