玄武岩纤维活性粉末混凝土氯离子渗透性能研究

STUDY ON CHLORIDE ION PENETRATION PERFORMANCE OF BASALT FIBER REACTIVE POWDER CONCRETE

本文通过在活性粉末混凝土(PRC)中掺入玄武岩纤维进行试验发现,玄武岩纤维能够提高RPC的氯离子抗渗透性能,当加入的玄武岩纤维长、径分别为12mm、13μm时RPC的抗氯离子渗透性能最高,抗渗性可以提高31.9%。

The corrosion of concrete by chlorides has been plaguing the majority of researchers and has brought enormous economic losses to the construction industry in various countries of the world. In this paper, basalt fiber was incorporated into reactive powdered concrete （PRC） and it was found that basalt fiber can improve the chloride ion permeation resistance of RPC. When the added basalt fiber length is 12mm and 13μm, the resistance to chloride ion penetration of RPC is the highest, Imperme-ability can be increased by 31.9%.
