Abstract
The “SPb SEC” Association has developed a standard of the organization (STO) “Refractories. Method for Determining Hydration Resistance.” The standard covers powders and articles based on magnesium oxide. The hydration resistance of powders is evaluated in terms of the change in the mass or in the grain composition of a sample after treating it with steam under pressure; the hydration resistance of articles is estimated from the change in their appearance.
