改性赤泥在市政道路工程中的应用
|
摘要
赤泥是以铝土矿为原料生产氧化铝过程中产生的极细颗粒强碱性固体废物。其应用于道路建设,不仅可消除环保隐患,且用渣量大,可保护和节约很多其他资源,创造新的经济价值。近年来,赤泥材料在道路工程中的应用越来越广泛。结合工程实例,委托相关单位对改性赤泥材料的路用性能和环境风险进行评估,确定改性赤泥作为路基填料的可行性。介绍改性赤泥路基设计、环保监测设施预埋,可供相关人员参考借鉴。
Red mud is a very fine-grained strong alkaline solid waste produced during the production of alumina from bauxite. Its application to road construction not only eliminates environmental hazards, but also has a large amount of slag, which can protect and save many other resources and create new economic value. In recent years, the application of red mud materials in road engineering has become more and more extensive. Combined with the engineering examples, the relevant units are entrusted to evaluate the road performance and environmental risks of the modified red mud materials, and determine the feasibility of the modified red mud as the roadbed filler. Introduce the design of modified red mud roadbed and the pre-burial of environmental protection monitoring facilities, which can be used for reference by relevant personnel.
