The investigating results are given in the article for the detailed mineral-petrographic analysis of the phase and structural transformation in the corundum, silicon carbide and graphite components of the samples taken at dierent parts of the concrete crucible in course of the extreme conditions testing (1600 °С, 10 hours, varying oxidation-reduction environment). It was defned that the main concrete's minerals components had the relative slag resistance which decreased in the consequence: graphite, silicon carbide, corundum, mullite, glass phase.Ill.12.
