An assessment of the corrosion and deterioration of concrete in environment (sewage facility) is proposedfrom the experimental results. Over the periods, changes to the roughened surfaces, mass change andcarbonation (neutralization) depth were observed. And a relation between carbonation depth and mass lossof concrete in this water-processing environment was shown a good correlation.
