INFLUENCE OF POLARIZATION ON CONDUCTIVITY OF CARBON FIBRE REINFORCED CEMENT
极化效应对碳纤维增强水泥（CFRC）导电性的影响

The polarization of carbon-fiber hardened cement paste (CFRC) at electric conduction is studied. The results show, the polarization has a notable effect on the electric conductivity of the CFRC.But the polarization can be controlled by adjusting the content of carbon fiber. the measuring voltage and current. The polarization decreases with curing age.So the electric resistence of CFRC can be measured by a direct current.
