The Study on the Durability Estimation of Concrete Contained Chloride ion by Individual and Combined Deterioration

Recently, corrosion of reforcement of reinforced concrete structures and carbonation is raised problem of durability because of exhaustion of river sand and rapid increase of sea sand and also, concrete structure of sea environment is attacked to combined deterioration according to penetration of chloride ion and carbonation, change of temperature, repetition of dryness and wetness. Therefore, In this study, data base were presented to solve the problem about using sea sand to concrete structure situated in combined deterioration environment by exposuring concrete specimen contained chloride ion under the individual and combined deterioration.
