Investigation of the material composition of technogenic magnesia material after hydration

Abstract

Of particular interest among various types of technogenic raw materials are highly magnetic wastes, which are promising secondary mineral raw materials for the production of refractory building materials, ceramics and a number of other types of products. Caustic magnesite dust of PJSC «Magnezit Combine» belongs to this group of waste, which has undergone intensive hydration in the dump. Technogenic raw materials are mainly weakly cemented fine-grained sandstones and fine-grained aggregates. The mineral basis of the material is magnesite, brucite and dolomite. The determination of the magnitude of the force required for the destruction of man-made material showed a variation in values from 0,5 to 3,9 kN.
