To promote the effective utilization of sludge and slag produced in nature and from human activities, this paper summarizes the research progress in the field of building materials on the basis of expounding their classification and characteristics. (1) Sludge and slag include silt, sludge and industrial waste residues. These three materials are mainly composed of SiO, which can be used to produce building materials after treatment and can also be used as admixtures, including roadbed admixtures. (2) Silt and sludge are widely used in building wall materials and roadbed materials, etc. Industrial waste residues can be used in the production and processing of green concrete and glass-ceramics. (3) In addition to continuing to use existing utilization methods, key treatment technologies and new treatment devices can be further developed according to the characteristics of sludge and slag. Moreover, observations and mechanistic analysis of the microscopic structure of industrial waste residues and research on strong and weak utilization methods based on the performance of building materials can be carried out, and more efficient and energy-saving excitation or activation technologies will be developed. These efforts will eventually lead to the development of functional building materials with excellent performance and environmentally friendly characteristics to achieve the differentiated utilization of silt, sludge, and industrial waste residues and realize the efficient transformation of resources. This paper provides useful insights for the application of sludge and slag in the field of building materials.
为促进自然和人为活动产生的污泥和矿渣的有效利用，本文在阐述其分类和特性的基础上，总结了建筑材料领域的研究进展。（1）污泥和矿渣包括淤泥、污泥和工业废渣。这三种材料主要由 SiO 组成，经过处理后可用于生产建筑材料，也可作为外加剂使用，包括路基外加剂。（2）淤泥和污泥广泛应用于建筑墙体材料和路基材料等，工业废渣可用于绿色混凝土和微晶玻璃的生产加工。（3）除了继续使用现有的利用方法外，还可以根据污泥和矿渣的特点进一步开发关键处理技术和新型处理设备。此外，可以对工业废渣的微观结构进行观察和机理分析，并研究基于建筑材料性能的强弱利用方法，开发更高效节能的激发或激活技术。这些努力最终将导致开发出具有优异性能和环保特性的功能性建筑材料，实现淤泥、污泥和工业废渣的差异化利用，实现资源的高效转化。本文为污泥和矿渣在建筑材料领域的应用提供了有益的见解。
