| Abstract: | 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. |
