Abstract: Waste foundry sand (WFS) is a fine by product generated in metal casting facilities. To beneficially reuse WFS is the ultimate solution coping with the vast volume disposal of WFS, which not only mitigates the burden on metal casting communities, but also eliminates potential impacts on the environment1 This article presents an overview on the environmental and physical characteristics of WFS, and its applications in prevailing construction-based products, such as cement concrete, hotmixing asphalt, controlled low-strength materials, cement, road subbase, embankment, hydraulic barrier and landfill liners. It reports that ferrous WFS is basically non-hazardous and will not incur unaccep table adverse environmental impacts. Reuses in above applications as construction materials lead to building products or engineered works at least technically equivalent to those using traditional materials. Thus, WFS is qualified for such beneficial reuses. = 废铸砂是铸造工业在金属制品的生产过程中次生出来的一种细颗粒固体废弃物。研究其作为一种资源进行合理再利用是当前处置废铸砂、保护生态环境的良好对策。本文对废铸砂的环境特征、物理性质及废铸砂作为建筑材料在多种建筑制品及工程中的资源化再利用进行了综述研究,涉及的再利用领域包括混凝土、热拌沥青混合料、低强度填料、水泥、路基、路堤、阻水帷幕(屏障)和衬垫。调查发现,次生于黑色金属(铁和钢)铸造生产线的废铸砂是一种无害固体废弃物,正确处置和科学利用,对环境不会产生二次污染,在以上建筑制品及工程中的应用能满足相关技术、性能要求,可以替代相关的材料进行资源化再利用。
