| 英文摘要 | To investigate the corrosion degradation law and service life of reinforced concrete in various salt solution environments, reinforced concrete specimens were semi-immersed in 3% Na2CO3(N3-0-0), 3% Na2CO3+3% NaCl (N3-Cl3-0) and 3% Na2CO3+3% NaCl+3% Na2SO4(N3-Cl3-S3)salt solutions. The electrochemical workstation was used for regular non-destructive testing, and the polarization curve and related electrochemical parameters were used as the macroscopic durability evaluation indicators, while microscopic analysis of steel bar corrosion products was performed in combination with SEM and EDS. In addition, the corrosion current density degradation model of GM (1,1) was established and compared with the modified GM (1,1)-Markov degradation model. The results showed that the prediction error of the GM (1,1)-Markov model was smaller and more accurate than that of GM (1,1). The reinforced concrete specimens in the N3-0-0, N3-Cl3-0 and N3-Cl3-S3 solutions reached the failure state in 3.08, 1.67, and 2.30 years, respectively, as predicted by the GM (1,1)-Markov model. According to ESM and EDS microscopic analysis of reinforcement, carbonate had no significant effect on reinforcement corrosion, chloride ions played a dominant role in reinforcement corrosion, and sulfate ion improved concrete's resistance to chloride ion corrosion. Based on GM (1,1)-Markov model, the failure and damage of reinforced concrete in saline soil areas can be quantitatively evaluated in the whole life cycle, which provides a theoretical basis for the early maintenance or reinforcing of reinforced concrete. |
