摘 要:通过循环加载压缩及电通量试验,研究了玄武岩纤维长度、养护龄期和循环加载压缩试验应力比对玄武岩纤维水泥基复合材料(BFCC)抗氯离子渗透性的影响。结果表明,随着养护龄期的增加,BFCC的6h电通量值逐渐减小;随着玄武岩纤维长度的增加,BFCC的6h电通量呈降低趋势,但是,当纤维长度从12mm增加到20mm时,BFCC的6h电通量降低速率减小;随着应力比的增加,BFCC的6h电通量呈先降低后增加的趋势,且应力比为0.2,BFCC的6h电通量值最小。Abstract:Basedonthecyclicloadingcompressionandelectricalfluxtests,theeffectsofthelengthofbasaltfiber,curingageandthestressratioofcyclicloadingcompressiontestontheresistancetochlorideionpermeabilityofbasaltfibercementcomposites(BFCC)werestudied.Theresultsshowthatwiththeincreaseofcuringage,the6helectricfluxvalueofBFCCgraduallydecreases.Whenthelengthofbasaltfiberincreases,the6helectricfluxofBFCCdecreases,however,whenthelengthofbasaltfiberincreasesfrom12mmto20mm,thedecreaserateof6helectricfluxofBFCCdecreases.Whenthestressratioincreases,the6helectricfluxofBFCCdecreasesfirstandthenincreases,andwhenthestressratiois0.2,the6helectricfluxofBFCCisthesmallest.
