4、rete quality and the existence of defects such as cracks. By using the proposed model,it was possible to estimate the progress of reinforcement corrosion and the corrosion crack generation timing in concrete . 1.Introduction Recently,the early deterioration of reinforced concrete structures has beco

5、me a major problem.Reinforcement corrosion due to chloride attack can be considered as one of the main causes. Various research projects have investigated this problem. However, there have been few evaluation techniques until now because of the variations in the quality of concrete, which is a porou

6、s material. The fact that experiments on deterioration take a long time has also been a contributing factor for the limited amount of data obtained thus far. In this study,construction of a simulation model for the deterioration of concrete structures due to chloride attack has been attempted.This model combines chloride and oxygen penetration models and a reinforcement corrosion model,taking into consideration variations in concrete - 2 - quality and the existence of defects such as cr
