| 英文摘要 | Corrosive crack influenced by coupled effects of chloride and sulfate often occurs in marine and saline ground environment, which has been a very serious threat to the durability of reinforced concrete structures. In this paper, accelerated potentiostatic corrosion test was used to investigate the corrosive crack of reinforced concrete mixing with different content of chloride ions and sulfate ions. The evolution of electric current and surface cracks width of reinforced concrete was tested. The results indicated that the higher concentration of chloride ions in mixing water had, the larger electric current intensity between the deformed steel bar and the stainless steel would be. 3D defects distribution of corrode reinforced concrete was also visually identified by X-CT technique. It showed that with sulfate ions added to the concrete including chloride ions, the fractions of micro defects became larger, while the fractions of the macro defects became smaller, which illustrated that the expansion pressure of the corrosion products was reduced and the concrete became more compact under the effect the sulfate ions. |
