摘　　要：研制了可预埋于混凝土结构中,能够实时监测混凝土中钢筋腐蚀电位、腐蚀速率、氯离子浓度和p H值的耐久性监测传感器,并对传感器的性能进行研究。研究结果表明:在测试的时间范围内,传感器能够较好地反映混凝土中氯离子浓度、p H值、钢筋腐蚀电位和腐蚀速率的变化趋势,可以用于监测混凝土结构的耐久性健康状况。A pre-embedded durability monitoring sensor, which of it could monitor corrosion potential of rebar, corrosion rate of rebar, chlorine ions concentration and pH for concrete structures was prepared. The properties were also investigated in concrete in laboratory. The results show that the monitoring results could reflect the variety trend of the corrosion potential of rebar, the corrosion rate of rebar, the chlorine ions concentration and the pH value of the concrete structures. It could be used to monitor the durability status of the concrete structures.
