Rebar Corrosion Rate Estimation of Reinforced Concrete Components Exposed to Marine Environment

Rebars embedded in reinforced concrete (RC) components were investigated. The rebar corrosion rate model is constructed to make macro quantitative evaluation and prediction of corrosion phenomena in RC components using regional marine environmental field exposure and laboratory accelerated corrosion method. The effect of the concrete strength and content of a mineral admixture on the rebar corrosion rate was studied by means of sampling corroded concrete components and measuring the rate of rebar corrosion under different exposure conditions. The mathematical model of the rebar corrosion rate in concrete components exposed to the marine environment is presented. Free chlorine ion contents on the rebar surface and rebar corrosion rates are linearly related.
