摘　　要：我国钢渣产量巨大,长期以来未能得到有效利用,导致了严重的环境污染问题,同时河砂资源也面临短缺。为了解决大量钢渣废弃物污染和日益枯竭的河砂资源问题,研究了钢渣对高延性地聚合物复合材料力学性能的影响,并探讨了钢渣作为细骨料时的复合材料性能,以及使用钢渣粉、矿渣和粉煤灰作为活性材料制备的钢渣粉-矿渣-粉煤灰三元地聚物高延性复合材料的抗压性能和拉伸性能。研究结果表明:钢渣替代细骨料对复合材料的拉伸强度有正向作用。当在前驱体中加入钢渣粉后,复合材料的抗压强度和弹性模量均得到了提高。因此,利用钢渣改性高延性聚合物复合材料具有重要的研究意义。China′s steel slag production is large,which has not been effectively used for a long time,causing serious pollution problems,and at the same time there is a shortage of river sand resources.In order to solve the problem of pollution of a large number of waste steel slag and provide a potential solution to the problem of increasing depletion of river sand,the influence of steel slag on the mechanical properties of high ductility geopolymer composites was studied,and the compressive properties and tensile properties of steel slag powder-slag-fly ash-based terpolymer high ductility composites prepared by steel slag powder,slag and fly ash as active materials were slag as fine aggregates.The results show that the replacement of fine aggregate by steel slag has a positive effect on the tensile strength of the composite.When steel slag powder is added to the precursor,the compressive strength and elastic modulus of the composite material are improved.Therefore,the modification of high ductility geopolymer composites with steel slag is of great research significance.
