| Abstract: |
| According to the corrosion circumstance of Duliujian river tide barrier, the concrete incorporating fly ash, superplasticizer and NaNO2 inhibitor is chosen in order to prevent the reinforcement in concrete from corrosion. The proportion of the concrete is designed.Compressive strength, permeability of the concrete to chloride ions and permeability of gases in the concrete are examined. Finally, a best proportion for the concrete of three bridges of Duliujian river gate is recommended. |
