摘　　要：高钛型高炉渣作为普通工业固废物,由于其TiO_(2)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。High-titanium blast furnace slag,as an ordinary industrial solid waste,is characterized by low activity and low utilization rate due to its high TiO_(2)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.
