Study of the refractory and mining waste usability to produce magnesium concrete

Бесплатный доступ

The article explores the possibility of using waste dumps of OJSC Group Magnezit enterprise in Satka for production of magnesium concrete. The fractional and mineralogical composition of this type of waste has been established. Fractions suitable for use as coarse and fine aggregate have been grouped. The possibility of using fractions, which are not included in the category of aggregates as a raw material for obtaining a magnesia binder by the combined method, has been identified. A hypothesis has been put forward on the principle of the best joint work of the hydration products of magnesia binder and magnesium-containing aggregates in the composition of a concrete mixture due to the similar mineralogy of these components.
