Abstract

In this paper, the corrosion of steel during the accelerated corrosion test was investigated through linear polarization method. The critical chloride ion concentration was determined according to the mentioned experimental results. Through the analysis of the experimental results of accelerated penetration test, the service life prediction equation of concrete structures was established. The 20V predicted results exhibited good compliance with the measured values, which indicated the reasonableness of the mentioned prediction method.

Keywords: Concrete, Accelerated Permeability Test, Service Life Prediction.
