Chloride Penetration into Concrete under the Coupling Effects of Internal and External Relative Humidity

Figure 7

Chloride content curves for concrete subjected to various external RH values (w/c = 0.5). (a) RH = 50%, (b) RH = 75%, (c) RH = 80%, and (d) RH = 100%. Control group represents that the chloride content was immediately determined after chloride attack.
