| 英文摘要 | The study on the properties of passive films in alkali-activated slag cement can provide a theoretical basis for the development and application of low-carbon and environmental friendly concrete materials. In this paper, the passivation behaviour of anti-corrosion rebar (AR) and normal reinforcing steel (NR) in sulfur-free simulated pore solutions of alkali-activated slag cement pastes was investigated using electrochemical, microscale techniques and molecular dynamics modelling. Results showed that the formation time, composition and thickness of the passive film were affected by the types of simulated pore solutions. Molecular dynamics further elucidated the reason for difference in the protective ability of passive film in three types of simulated pore solutions. The results of protection capability of two kinds of rebar obtained from molecular dynamics were consistent with those of electrochemical impedance spectroscopy (EIS). |
