【 摘 要 】
A most promising development direction of heat-resistant concrete is the development of heat-resistant concretes based on lime-slag binder with highly-aluminous slag aggregates. One of the main process development directions of heat-resistant concrete for products with increased heat resistance is the lowering of the contents of expensive components: aggregates, binders, hardeners and powdered additives by various industrial wastes. Such replacement could significantly reduce the prime cost of heat-resistant concretes, and in some cases increase their operating temperature and durability. Based on experimental studies, efficient compositions of heat-resistant lime-slag concrete has been developed, based on chamotte, slag from aluminothermic ferrochromium and ferrotitanium process, with 1100-1300°C operating temperature.
