Reinforced concrete is an excellent composite system combining both steel and concrete However, when a crack is formed in concrete both water and oxygen can easily approach to the surface of steel in concrete, and this causes corrosion of steel reinforcement The corrosion reduces the performance of reinforced concrete structure. This paper aims to evaluate the corrosion rate of steel in concrete quantitatively, in chloride environment The results show that corrosion rate of reinforcing steel bar can be predicted numerically by applying different chloride boundary conditions to cracked portion and other surfaces. The effect of temperature is also examined by both experiment and computer simulation
