Modification of Magnesia Binder with Iron Ore Concentrate

Article Preview

Abstract:

On the basis of the experimental data, a method and mechanism for modifying magnesia binders with iron ore concentrate has been proposed. It consists in form of a material reinforced fine-crystalline structure with elongated magnesium oxychloride crystals, which improves its physical and mechanical characteristics. The components of iron ore concentrate and magnesia binder, having improved sorption properties, significantly accelerates the formation of such a structure.
