摘要
针对我国金属矿山用水泥作充填胶凝材料成本高的问题，通过试验研究，肯定了赤泥胶凝剂做充填胶凝材料的多种优点，即这种胶凝剂具有早期强度高、后期强度稳定，无论从凝结时间还是强度指标都完全能满足矿山充填要求；此外，其主要原料为工业废料，价格仅为水泥价格的1／3，因此具有良好的社会效益和经济效益。
Aimed at the high cost of cement which was used as a cementitious material of filling in chinese metal mines, through tests and investigation, it was confirmed that Red mud cementitious agent used as cementitious material of filling has many merits such as being high in early strength, stable in late strength, able to meet the reguirements of filling in mines, either in setting time or in strength indexes; further more, its major raw materials are industrial wastes and its price is only one thind of that of cement so that it has good social and economic benefits.
