摘要

The corrosion of reinforcing steel in concrete is the main factor for thedeterioration of durability. The monitoring of corrosion of the steel bar and the environmentcondition of the corrosion can provide the basic data for the estimation of the residuarycapacity and durability of reinforced concrete structure. Through investigating the corrosionof the resistance probe in the concrete and appraising the penetrability of concrete using RCMmethod,the resistance-probe method monitoring the corrosion is presented and comparedwith electrochemical probe method. The results show that whether in the simulation liquid orin the concrete,the accretion of corrosion is corresponding to the impedance increases.Comparing the results of electrochemical-probe method (EPM) and electrical resistancemethod (ER),the same corrosion evaluation can be obtained. So,it is feasible to use ER tomonitor the corrosion of steel bar in the concrete and environment condition of the corrosion.
