铁尾矿在建筑材料中的应用研究进展

Research Progress on Durability of Iron Tailings Concrete and Its Application in Building Materials

铁尾矿作为工业固体废弃物,其产量呈逐年递增趋势,大量堆积的铁尾矿对环境造成了严重破坏,对人民群众生命财产和健康构成了威胁,如何实现铁尾矿废弃物资源化利用已成为我国可持续发展过程中不可回避的问题。以铁尾矿在建筑材料中的应用为目标,分别从铁尾矿理化性质分析、用作水泥熟料、制备混凝土、制备新型轻质建材四个方面进行全面阐述,分析现阶段铁尾矿资源化利用最新进展,总结铁尾矿应用最新研究成果,为铁尾矿在建筑材料中高附加值利用提供参考,同时也助力“碳达峰、碳中和”目标的实现。

As an industrial solid waste,the output of iron tailings is increasing year by year.In addition,the massive accumulation of iron tailings has caused serious damage to the environment and poses a threat to people's lives,property,health and life.How to realize the resource utilization of iron tailings waste has become an unavoidable problem in the process of sustainable development in China.Aiming at the application of iron tailings in building materials,this paper comprehensively expounds the four aspects of physical and chemical property analysis of iron tailings,use as cement clinker,preparation of concrete and preparation of new lightweight building materials,analyzes the latest progress of resource utilization of iron tailings at the present stage,summarizes the latest research results of iron tailings application,and provides reference for the high value-added utilization of iron tailings in building materials.At the same time,it also helps to achieve the goal of carbon peak and carbon neutrality.
