    (1)EAFD的消耗和處理已經成為世界性難題,有價金屬的二次回收能夠解決高回收價值EAFD的處理問題,但是無法處理回收價值偏低的EAFD。鑒于水泥混凝土在工業固廢處理領域的貢獻,可將有價金屬含量低的EAFD應用于水泥混凝土領域。
    (2)EAFD中的ZnO對水泥具有明顯的緩凝效果,但EAFD中的其他成分是否對水泥水化有影響還需進行深入研究。
    (3)EAFD中的重金屬是EAFD在水泥混凝土領域應用時需要重點考慮的問題之一。已有研究表明,控制好EAFD中Pb的含量,水泥可以對其他有害金屬進行有效地固化。因此,根據EAFD中有價金屬的含量,合理選擇EAFD的回收處理方式非常必要。
    (4)適量的EAFD對水泥混凝土具有緩凝、降低水化熱、提升力學性能等優點。需要注意的是:①與粉煤灰、礦渣等材料相比,EAFD的屬地化特征明顯,其成分受原料和工藝的影響較大,故不同地區的EAFD對水泥混凝土性能的影響效果是否一致還需要進行深入的評價研究;②實際應用時,應根據EFAD中的ZnO含量合理考慮其回收利用方式。
