对电炉镍铁渣（EFS）基地聚合化学键合陶瓷材料（EFS-GCBCs）的性能进行了综述，发现该材料由于使用碱激发剂很容易碳化而发生结构破坏；此外，关于关键组分镁含量对材料性能及水化机理影响方面的研究较少，存在材料制备机理不够透彻等缺陷。因此，基于EFS富含镁质的特性，提出利用EFS制备镍铁渣基磷酸镁化学键合陶瓷材料（EFS-PCBCs）的设想。磷酸镁化学键合陶瓷材料（PCBCs）具有材料凝结速度快、早期强度高、高耐盐冻、抗腐蚀、低收缩及良好的混凝土兼容性等优点，而EFS-PCBCs与传统PCBCs相比，显著降低了PCBCs制备成本，该方法可为EFS高效综合利用提供一种新的研究思路。

The preparation of electric arc furnace-derived ferronickel slag (EFS) based geopolymer chemically bonded ceramics (EFS-GCBCs) and their properties are reviewed.It is found that EFS-GCBCs are easily damaged by carbonization due to the use of alkali activators.In view of the magnesium rich characteristics of EFS,it is proposed to use EFS to prepare EFS-magnesium phosphate chemically bonded ceramics (EFS-PCBCs).PCBCs possess superior performance over Portland cement,such as faster setting speed,higher early strength,higher salt freezing resistance,better corrosion resistance,lower shrinkage and better concrete compatibility etc.Compared to traditional PCBCs,the prepared EFS-PCBCs will be lower in preparation cost.This way can provide a research idea for efficient and comprehensive utilization of EFS.
