Analysis of Testing Methods for Chloride Ion Permeability in Marine Concrete

Chloride ion permeation is the most important factor for durability of concrete in marine environment. Therefore, it is the basic on durability design of concrete structures to choose reliable and accurate testing method for chloride ion permeability in concrete. In this paper, according to transport process reflect practical or impractical migration of chloride ion in concrete, testing methods were classified. The principle and application range of each method were analyzed, and the existing problems for each method are discussed. In order to adopted test methods for chloride ion permeating in concrete are scientific and accurate.
