Determination of quantitative content corrosion products on concrete products surface

Abstract

The article deals with the processes of corrosion in reinforced concrete supports of the catenary and describes the reactions accompanying corrosion of steel reinforcement. The experiment of electrochemical corrosion made of samples with varying degrees of corrosion of steel reinforcement is described. Samples with different corrosion degree of steel reinforcement are made. Spectral analysis is performed to determine the quantitative content of corrosion products on concrete surface. The analysis of results confirmes the dependence of the corrosion products concentration on the concrete surface with the removal of metal from the steel reinforcement volume. The calibration dependence of the iron determination on concrete surface is obtained.
Conclusions are made about the possibility of using mobile
spectral analyzer in conjunction with the presented methodology.
