| Abstract: |
| The influences of admixture of Dura fiber on corrosion of reinforcing bar in concrete are discussed by using the parameters of corrosion weightless rates and half cell potential. Results of indoor laboratory tests show that the corrosion weightless rates decrease and the half cell potential increases with increase of dosage of Dura fiber. It is shown that adding Dura fiber into reinforced concrete will raise anti-corrosion behavior of the reinforcing bar. |
| Key words: polynomial fiber dosage corrosion weightless rates of reinforcing bar half cell potential of reinforcing bar reinforced concrete |
