摘要	Electrochemical impedance spectrum has been used in this work to study the critical chloride concentration for the rebar corrosion in fly ash concrete. The analysis and criteria for the critical corrosion point of rebar have been interpreted, and the surface morphology of the corroded rebar has been studied using SEM. The influences of the wet-dry cycling period and the fly ash content on the impedance spectra and the critical chloride concentration have been discussed respectively. It shows that the critical corrosion point can be precisely manifested by impedance spectra; the resistance of the concrete layer increases with increasing period of wet-dry cycling and increasing content of fly ash, which can be observed as translation of the spectra to the right on the complex plane; the critical chloride concentration tends to increase with increasing period of wet-dry cycling; the critical chloride concentration for rebar corrosion can be increased by a small dosage of fly ash in the concrete.
