摘　　要：进行石墨导电混凝土的导电特性实验，分析养护龄期、石墨质量分数、电源性质和应力对石墨导电混凝土电阻率的影响．结果表明：养护龄期对低质量分数的石墨导电混凝土影响较大，对高质量分数的石墨导电混凝土影响较小；交流电作为电源能有效避免极化效应的产生，所得结果更接近于真实值，在实际应用时也更节省能量；石墨导电混凝土的渗滤阈值为10％～15％；石墨导电混凝土的压敏性不很明显，当石墨质量分数为10％时可以定性使用．Trial studies are applied to conductive property of graphite electrically conductive concrete(GECC).Influence of curing age,admixture amount of graphite,character of power supply and outer stress on GECC resistivity is analyzed.Significant effect of curing age on low graphite content GECC happens,but little on high.Polarization effect can be avoided effectively using alternating current,which makes the estimates more precise and saves more energy.Percolation threshold of GECC is between 10% and 15%.Compression sensibility of GECC is not obvious,but it also can be applied qualitatively for GECC of 10% content.
