The purpose of this study is to evaluate salt attack durability of the concrete structure which has experienced the fire. Mechanical properties and chloride ion diffusivity of concrete specimens were measured after 2 hours heating at 200℃, 400℃, 600℃, 800℃. FEM analysis was conducted to predict the life expectancy of RC structure using the property values by a series of experiment.
