摘　　要：再生混凝土由于再生骨料自身的缺陷:富含杂质、孔隙率高、吸水性大、强度低等,限制了其应用范围。通过试验研究,得出利用聚丙烯纤维和硅粉对再生混凝土进行强化,可以明显改善其力学性能,提高其强度;研究了聚丙烯纤维和硅粉掺量对再生混凝土强度的影响,为实际工程应用,提供了理论依据。The recycled concrete has limited its＇ range of application because of the defects of the recycled aggregate： rich in impurity, high in porosity, large in water absorbability, low in strength, The intensified test research shows that the utilization of polypropylene fiber and silica fume can obviously improve the recycled concrete＇s mechanics performance and increase its strength. The influence of different content of polypropylene fiber and silica fume on the strength of the recycled concrete is also studied in the paper. It can offer the theoretical foundation for the actual project application.
