摘要
大宗固体废弃物,包括钢渣、矿渣、尾矿、淤泥、建筑垃圾、玻璃渣等材料,是以氧化硅、氧化铝、氧化钙等为主的无机材料,与无机保温材料组分相似、结构相近,是替代传统天然原料的主要来源。根据无机保温材料的结构特点,结合大宗固体废弃物的物化特征,综述了大宗固体废弃物在固废基保温功能填料、固废基掺合材料和全固废基保温材料等建筑节能领域的研究进展,讨论了大宗固废高附加值利用过程物化特性研究、组分调制、多固废协调作用的技术可行性,提出了固废基无机保温材料的发展趋势。
Bulk solid wastes,including steel slag,slag,tailings,sludge,construction waste,glass slag,and other materials,is a mixture of inorganic materials mainly composed of silicon oxide,aluminum oxide,calcium oxide,and so on.These wastes have similar compositions to inorganic thermal insulation materials and are the main source of replacing traditional natural raw materials.Based on the structural characteristics of inorganic thermal insulation materials and the physical and chemical characteristics of bulk solid wastes,this paper summarizes the research progress of bulk solid wastes in the field of building energy conservation such as solid waste-based thermal insulation fillers,solid waste-based admixtures,and total solid waste-based thermal insulation materials,and discusses the technical feasibility of reaearch on physicochemical characteristics,component adjustment,and coordinated action of multiple solid wastes.Finally,the development trend of solid waste-based inorganic thermal insulation materials is proposed.
