| 摘 要： | 以钢渣、矿渣和脱硫石膏为原料制备胶凝材料，研究了铅离子浓度和养护工艺对胶凝材料固铅效果的影响，并利用XRD和SEM对固铅胶凝材料的水化产物进行了分析。结果表明，冶金渣胶凝材料相对于水泥具有更高的固铅效率。冶金渣胶凝材料水化产物中存在的多种协同作用是其固铅效率显著高于水泥的重要原因。

| Abstract: | Taking steel slag powder (SS), blast furnace slag (BFS) and desulfurization gypsum (DG) as the ingredients for cementitious materials, the effect of the concentration of lead ions and curing process on the lead fixation were studied. The hydration products of lead-containing cementitious materials were analyzed by XRD and SEM. Cementitious materials prepared with solid waste have higher lead fixation efficiency than cement materials. The various synergistic effects existing in the hydrated products of cementitious materials, are the primary reason for its superior lead fixation efficiency than that of cement. |
