Effect of Imposed Rebar Corrosion Electricity on Mortar Percolation Structure

Based on the method of accelerated-reinforcement-corrosion by constant DC,the effet of imposed corrosion electric quantity on mortar percolation structure was studied with electrochemical impedance spectroscopy.The results showed that the hydraulic radius and di-charge-layer capacity of the mortar specimen reduced and the charge transmission impedance and tortuosity increased with the increasing of the imposed corrosion electric quantity at earlier stage.
