摘要：为了研究玄武岩纤维对活性粉末混凝土耐久性的影响，进行了9组玄武岩纤维活性粉末混凝土（RPC）和3组素RPC的氯离子渗透试验以及1组玄武岩纤维RPC的碳化性能试验。试验结果表明，素RPC的电通量为104~120 C，氯离子渗透性极低，玄武岩纤维RPC的电通量均小于100 C，氯离子渗透性可以忽略。当水胶比为0.22、玄武岩纤维体积掺量为0.10%时，试件的抗氯离子渗透性能最好。玄武岩纤维RPC试件具有良好的抗碳化性能，其28 d碳化深度为0。 Abstract: In order to investigate the influence of the basalt fiber on the durability of reactive powder concrete (RPC), chloride ion penetration test of nine groups of RPC containing basalt fiber and three groups of RPC without fiber was carried out, and carbonization test of one group of basalt fiber RPC was performed. The results show that the electrical flux of RPC without basalt fiber varies from104~120 C, and the chloride ion permeability is very low. The electrical flux of basalt fiber RPC is less than 100 C, and the chloride ion permeability can be ignored. When water-binder ratio is 0.22 and volume fraction of basalt fiber is 0.10%, the chloride ion permeation resistance of specimens is the best. The basalt fiber RPC has good carbonization resistance, and the carbonation depth of 28 d is 0.
