摘要：

Corrosion of steel reinforcement is the most serious threat to the service life of modem reinforced concrete structure and the corrosion behavior of the steel reinforcement has a close dependence on the chemical environment at the steel/concrete interface. Among all the species which can affect the corrosion rate, H+ is of the greatest influence on the stability of the steel bars. However, the in-situ measurement of pH value at steel/concrete interface is still underway. In this paper fabrication of Ir oxide electrode which serves as the pH probe working at the steel/concrete interface was explored.
