FIELD: refractory and building materials. SUBSTANCE: invention can be used in manufacture of concretes, piece articles, ramming mixtures and gunned materials. Mix contains, wt %: fused corundum fraction 3.2-0.5 mm modified with zircon in the course of fusion at aluminum oxide-to-zirconium oxide weight ratio (1.6-1.7):1, 33-50; common fused corundum fraction 100- 200 mcm, 10-20; disperse filler in the form of alumina fraction below 0.063 mm and refractory clay at ratio 2:1, 25-30; silicon carbide or graphite additive or their mixture, 10-15; phosphate binder, 5-7. EFFECT: prevented weakening and increased erosion resistance. 1 tbl |
