| 要旨 | Under an accelerated artificial aggressive conditions,the corrosion-protection behavior of zinc coating steel fibers in reinforced concrete specimens was studied.In general,the results showed that in the zinc coating steel fiber reinforced concrete matrix,although amount of diffused chloride ions were 10 times more than threshold limit to initiate corrosion,the embedded steel bars were not corroded.However,at the same conditions the steel bars which were not incorporated by zinc coating steel fibers in concrete matrix were seriously corroded.On the other hand,galvanized steel fibers had a sacrificial anode role to protect corrosion of reinforced concrete and also could tolerate a higher chloride concentration than no-fiber concrete matrix. |
