Magnesium Oxide Properties and Applications

This paper presents the results of research on the utilization of slag produced as the waste material of metallic magnesium production. This material is a fine powder with a high magnesium content. The characterization of slag was performed by XRD, DTA and TG analysis. Chemical composition and mechanical properties of slag were also determined. By using a mixture this slag and limestone aggregate, it is possible to obtain dry mortar which, mixed with water, gives a material fully satisfying for plastering mortar. By adding inorganic pigments (Fe2O3, Ca2O3, etc.) decorative mortars are obtained, and when they are spread over the foundation made of brick or concrete, they retain their colour on the entire coating and surface of the mortar.
