Concrete material is a durable material, but it is essentially a non-uniform microporous material. The penetration of corrosive media from pores is the main cause of erosion. The erosion in media such as carbon dioxide, water, chloride ions, sulfates, etc. Under the action, the concrete will accelerate the destruction and the service life will be greatly shortened. Especially in the marine environment, the salinized areas in the west and the northern areas where deicing salt is sprayed, the corrosion of infrastructure is relatively serious. The corrosion of concrete structures in its interior and in a dry environment is slow, and the harmfulness has not attracted enough attention.
