摘要
伴随着城市垃圾处理量加大,生活垃圾焚烧炉渣产量呈上升趋势。为探索炉渣和红黏土共混在土木工程中应用的可行性,文章系统地分析了炉渣不同掺量对红黏土力学特性及重金属污染因子淋滤行为的影响。当炉渣的掺入量逐渐增多时,重金属的浸出量也会明显上升,特别是在掺入量超过30%的情况下。研究表明,适当控制炉渣掺量可以兼顾力学性能提升和环境安全性。
With the increase of municipal waste treatment,the output of solid waste incineration slag shows an increasing trend.In order to explore the feasibility of the blending of slag and red clay in civil engineering,the effects of different slag contents on the mechanical properties of red clay and leaching behavior of heavy metal pollution factors were systematically analyzed.When the amount of slag incorporation gradually increases,the leaching amount of heavy metals will also increase significantly,especially when the amount of incorporation exceeds 30%.The research shows that proper control of slag content can both improve mechanical properties and environmental safety.
