摘要：采用再生微粉和工业废渣固化淤泥，研究了固化材料的类型（工业废渣基固化材料A、工业废渣-再生微粉基固化材料B）和掺量（5%、10%、15%、20%）、淤泥含水率（17%、45%、70%）对固化淤泥力学性能的影响，并进行了XRD和SEM分析，探讨了固化机理。结果表明：固化材料B的抗压强度比固化材料A的抗压强度低；固化材料B固化淤泥的无侧限抗压强度比固化材料A固化淤泥的无侧限抗压强度低；随着固化材料掺量的增加，固化淤泥的无侧限抗压强度增大；随着淤泥含水率的增加，固化淤泥的无侧限抗压强度降低；综合考虑经济性、节能环保和固化淤泥的力学性能，推荐采用固化材料B作为淤泥的固化材料。 Abstract: The effects of the types(industrial waste slag based solidified material A, industrial waste slag-recycled micropowder based solidified material B) and contents(5%, 10%, 15%, 20%) of solidified materials and the moisture content of the sludge (17%, 45%, 70%) on the mechanical properties of the solidified sludge were studied. The solidified mechanism was discussed by XRD and SEM analysis. The results show that the compressive strength of solidified material B is lower than that of solidified material A. The unconfined compressive strength of sludge solidified by solidified material B is lower than that of sludge solidified by solidified material A. The unconfined compressive strength of solidified sludge increases with the increase of the content of solidified material. With the increase of moisture content of sludge, the unconfined compressive strength of solidified sludge decreases. Considering the economy, energy conservation and environmental protection and the mechanical properties of solidified sludge, solidified material B is recommended as the solidified material of sludge.
