综述了碱激发固废胶凝材料的力学性能与水化产物的研究现状,针对传统硅酸盐水泥生产的高能耗和高污染问题,探讨其作为低碳建材的潜力.以高炉矿渣、钢渣和粉煤灰等常见固废为例,分析不同碱激发剂对3 种固废强度的影响,讨论了养护条件对碱激发固废强度的影响.从微观测试角度讨论3 种碱激发固废产物的结构与组成,对未来研究方向进行了展望.
Research progress on mechanical properties and hydration products of alkali-activated solid waste
This paper reviews the current research status of the mechanical properties and hydration products of alkali-activated solid waste cementitious materials,and discusses their potential as low-carbon building materi-als in light of the high energy consumption and pollution associated with traditional Portland cement produc-tion.Taking common solid wastes such as blast furnace slag,steel slag,and fly ash as examples,the study ana-lyzes the effects of different alkali activators on the strength of these three types of solid waste;it also discusses the impact of curing conditions on the strength of alkali-activated solid waste.Furthermore,the structure and composition of the products from the three types of alkali-activated solid waste are examined from a microscopic testing perspective,providing insights into future research directions.
