中文摘要:
      在水泥基复合材料中参入碳纤维和钢渣,以研究复合水泥基材的导电性能,结果表明,碳纤维能够显著改善水泥基材的导电性,碳纤维体积率为1.2%时,其导电性能最佳,且碳纤维对试件导电稳定性有显著影响;在碳纤维水泥基材中参入钢渣并不会显著影响试件导电性,会显著影响导电稳定性;抗压和抗折试验结果表明利用导电性判断构件是否损伤(开裂)及损伤程度在试验上是可行的。
英文摘要:
      In this paper, carbon fiber and steel slag are used in cement matrix composite materials to study the electrical conductivity of composite cement substrate. It is concluded that carbon fiber can significantly improve the electrical conductivity of cement substrate. When the volume ratio of carbon fiber is 1.2%, its electrical conductivity is the best.The inclusion of steel slag in carbon fiber cement substrate does not significantly affect the electrical conductivity of the specimen, but significantly affects the electrical stability.The results of compressive and flexural tests show that it is feasible to use electrical conductivity to judge whether the component is damaged (cracked) and how much it is damaged.
