摘　　要：通过大掺量超细工业废渣及采用普通工艺成功制备了3类超高性能水泥基复合材料，分别测试了其7、28、90d的抗压强度和抗折强度，并对其进行了分析，讨论了玄武岩纤维对其力学性能的影响。结果表明：玄武岩纤维体积掺量为0．1％～0．5％且以层布方式]JnA时可以明显提高强凝土的抗折强度和抗压强度，表现出良好的增强效果。Three kinds of ultra-high performance cement composites（UHPCC） were successfully prepared by substitution of ultra-fine industri- al wast for large quantity of cement and using the conventional technology.The compressive strength and flexural strength were tested when the concretes were 7,28,90 d.The influence of basalt fiber on the mechanical performance of UHPCC were discussed.Results showed that layered basalt fibere was benefit for the accretion of the flexural strength and compressive strength of UIqPCC,the optimal volume friction of basalt fiber is0.1%-0.5%.
