摘要

摘要: 高钛型高炉渣作为普通工业固废物，由于其TiO₂含量较高且主要矿物成分均为结晶性较强的稳定性矿物，致使其活性较低、利用率不高，大多处于堆积状态。为更好地解决高钛型高炉渣活性较低、利用率不高的问题，从高钛型高炉渣粉特性入手，阐述了高钛型高炉渣粉作为辅助性掺合料机械活化、化学激发、复合活化激发、复合其他掺合料共同激发的四种活性激发方式，并分析了四种活性激发方式的激发机理。同时，探讨了高钛型高炉渣粉作为辅助性掺合料对混凝土工作性能、力学性能、耐久性能的影响研究现状与影响机理，评价了高钛型高炉渣粉的环境性能及经济效益，指出了高钛型高炉渣粉活性激发存在的不足与活性提升发展方向，为高钛型高炉渣实现更好的资源化利用提供参考。

Abstract: High-titanium blast furnace slag, as an ordinary industrial solid waste, is characterized by low activity and low utilization rate due to its high TiO₂ content and predominantly crystalline and stable mineral components, resulting in its accumulation. To better address the issues of low activity and utilization of high-titanium blast furnace slag, this review commences with an analysis of its powder properties and elaborates on four activation methods: mechanical activation, chemical activation, composite activation, and combined activation with other admixtures. The activation mechanisms of these four methods are also analyzed. Furthermore, the current research status and mechanisms of the influence of high-titanium blast furnace slag powder as an auxiliary admixture on the workability, mechanical properties, and durability of concrete are discussed. The environmental performance and economic benefits of high-titanium blast furnace slag powder are evaluated, and the shortcomings and future directions for enhancing its activity are pointed out. This study provides a reference for achieving better resource utilization of high-titanium blast furnace slag.
