FIELD: refractory materials. SUBSTANCE: refractory concrete mixture comprises 50-85 wt.-% of refractory filling agent based on aluminum oxide and 15-50 wt. -% of binding agent of the following composition, wt.-%: aluminum oxide-base refractory component, 84-97; sodium tripolyphosphate, 1.8-15.0; oxalic acid, 0.2-2.0. Oxalic acid in combination with sodium tripolyphosphate forms sol that promotes to friction decrease between particles and confers the enhanced fluidity to concrete solution and absence of chemically bound moisture ensures to intensify the rate of thermal treatment of lining concrete solution. EFFECT: improved properties of mixture. 1 tbl
