Corrosion Assessment in Rebars of RC Structures Using PZT patches
Objective:
This simulation experiment is based on experimental data measured during actual accelerated corrosion tests carried out on reinforced concrete (RC) structures (embedded rebar).
Apparatus Used:
1. An empty tank
2. Brine solution
3. PZT patch
4. Power supply
5. Copper rod as cathode
6. Copper rod holder
7. Concrete cube containing a rebar as anode
