杜拉纤维对混凝土中钢筋腐蚀性能的影响

Influences of Dura fiber on corrosion of reinforcing bar in concrete

用钢筋腐蚀失重率和半电池电位两个参数探讨了杜拉纤维掺量对钢筋混凝土中钢筋腐蚀的影响.室内试验结果表明,随杜拉纤维掺量的增加,钢筋腐蚀失重率降低、钢筋半电池电位增加.在钢筋混凝土中适量掺入杜拉纤维能有效地抑制钢筋腐蚀.

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.
