本文研究结果可归纳为：与无纤维RPC相比，钢纤维的加入大大增加了活性粉末混凝土的抗折强度和疲劳寿命。
The study results in the paper can be conclude that the bending strength and fatigue life of RPC with steel fibre are much higher than those of plain RPC.
对大掺量矿物细粉活性粉末混凝土收缩、钢纤维锈蚀、抗碳化性能、抗氯离子渗透等性能进行了试验研究，并通过孔结构和扫描电镜实验对其微结构进行分析。
In this paper, Shrinkage, steel fiber corrosion, carbonation resistance and chloride-permeation resistance of high volume fine mineral mixture of RPC has been investigated by the experiment.
当钢纤维体积含量超过3.5%后，活性粉末混凝土抗压强度下降，劈拉强度略有提高，而抗折强度仍有明显的提高。
When the steel fiber volume fraction is higher than 3.5%, its compressive strength decreases, the splitting tensile strength increases slightly, however, its flexural strength increases obviously.
