The Investigation of Deteriortion of Concrete Structures due to the De-icing Salts

융빙제 사용으로 인해 열화된 콘크리트 구조물의 내구성 조사

The study was performed for the purpose of obtaining the fundamental data to improve the durability of concrete structures due to de-icing salts. To assume the degree of concrete deterioration, soluble chloride content in concrete, the depth of carbonation and compressive strength of core specimens were measured. The porgress of corrosion of concrete bridge was electrochemically monitored. The results show that the concrete structure was deteriorated and reinforced steel in concrete was corroded due to de-icing salts.
