摘　　要：钢渣是炼钢过程中的副产物,作为废弃物堆存不仅造成了资源的浪费,还对生态环境造成了严重威胁。将钢渣用于道路水泥稳定层,具有明显的经济效益和环境效益。本文系统概述了钢渣的来源及理化性质、水化特性及添加至道路水稳料中对凝结时间、强度、收缩及耐久性的影响,并对其机理进行了分析。在水稳料中添加钢渣可明显提升水稳层的强度,减缓体系的收缩。此外,采用提高养护温度、考虑多种固废间的协同效应等手段可进一步增加钢渣基水稳料的性能。最后,提出了将钢渣应用于水稳料中需要重点考虑的问题和未来的研究发展方向,为钢渣的进一步研究和应用提供参考。Steel slag,a by-product of the steelmaking process,and its stockpiling as waste not only causes a waste of resources but also poses a serious threat to the ecological environment.The use of steel slag for road cementitiously stabilized layers(CSLs)has obvious economic and environmental benefits.This paper systematically outlines the source and physical and chemical properties of steel slag,its hydration characteristics,and the effects of adding it to CSLs on setting time,strength,shrinkage,and durability,and analyzes its mechanism.Adding steel slag to the CSLs can significantly improve the strength of the CSLs and slow down the shrinkage of the system.In addition,the performance of steel slag-based CSLs can be further increased by using higher maintenance temperatures and considering synergistic effects between multiple solid wastes.Finally,the problems to be considered and the future research and development direction of applying steel slag in CSLs are proposed to provide a reference for further research and application of steel slag.
