摘 要:制备了钢纤维石墨导电混凝土,进行了电流类型及电压大小对电阻率影响的相关试验。研究发现,交流电源供电时,导电混凝土试件的电阻率小于直流电源供电时的电阻率,两者的差值随电压的增加而减小;无论是交流电源还是直流电源供电(电压在60V以下),试件电阻率均与电压成反比,两者呈二次抛物线关系,电阻率的变化幅度随电压的增加而减小。
Abstract:The electric conductive concrete (ECC) was prepared, the influence of current type and voltage size on the resistivity was studied by related experiments. The results showed that the resistivity of ECC under AC power is smaller than that of ECC under DC power at the same voltage. The difference between two resistivity reduces as the increasing of voltage. No matter the power supply is AC or DC, the resistivity and the ratio of resistivity are both inversely proportional to voltage.
