The results of research on obtaining a new composition of chemically resistant, refractory concrete mixture are presented. The basis of the resulting mass is production waste, which is a slag of electrothermal reduction of niobium pentoxide — crushed and purified fused alumina — electrocorundum, ferrosilicon slag, ferrochrome slag, refractory aluminosilicate mortar and refractory clay. High chemical resistance, fire resistance, mechanical strength, hardness and wear resistance determine the scope of its application—the production of chemically resistant, refractory concrete.

用冶金废料生产耐火耐火混凝土混合物及其理化特性

给出了获得新的耐化学腐蚀的耐火混凝土混合物组成的研究结果。生产废料的基础是生产废料，它是电热还原五氧化二铌（压碎和精制的熔融氧化铝）电刚玉，硅铁渣，铬铁渣，耐火硅铝酸盐砂浆和耐火粘土的渣。高耐化学性，耐火性，机械强度，硬度和耐磨性决定了其应用范围-生产耐化学性的耐火混凝土。
