聚丙烯纤维混凝土抗钢筋腐蚀试验研究

Reinforcement anticorrosion test of fly ash concrete containing polypropylene fibers

对掺聚丙烯纤维的粉煤灰混凝土抗钢筋腐蚀能力进行了试验研究,比较了纤维掺量分别为0、0．8、 1．1 kg／m3的聚丙烯纤维混凝土抗钢筋腐蚀的能力．试验研究表明,粉煤灰混凝土的抗钢筋腐蚀能力随旨聚 丙烯纤维掺量的增加而增加,当混凝土中纤维的掺量达到0．8 kg／m3时,抗钢筋腐蚀能力较基准混凝土提高 16％,当纤维掺量达到1．1 kg／m3时,抗钢筋腐蚀能力较基准混凝土提高43％．

The reinforcement anticorrosion behavior of fly ash concrete containing polypropylene fbers was examined, and the influence of polypropylene fiber content (0, 0.8,1.1 kg/m3) on reinforce nent anticorrosion behavior of fly ash concrete was investigated in this paper. The test result shows that the reinforcement anticorrosion capacity of fly ash concrete is increased with the increase of polypropylene Iber content. An reinforcement anticorrosion capacity increase of 16 percent is achieved when 0.8 kg/m3 polypropylene fibers is added, while an anticorrosion capacity increase of 43 percent is reached when 1.1 kg/m3 polypropylene fibers is added into fly ash concrete.
