Hydration, rheological, and bonding properties of water suspensions of periclase
- 40 Downloads
From the viewpoint of the volume phase composition we studied and analyzed the hydration and dehydration of cements based on electrofused MgO.
We also studied the influence of the dispersion factors of the medium (water and solutions of HCl and magnesium chloride of various concentrations) on the hydration and rheological and bonding properties of the suspension. The suspensions of periclase manifest plastictype flow, and are characterized by thixotropic breakdown.
The strength properties of the castings, determining the bonding properties of the periclase suspension, depend on the type and concentration of the dispersion medium, the volume content of bonded liquid, the conditions and duration of setting, the density of the semifinished article (greenware), and the dispersion of the solid phase.
