Research on Stress Corrosion of Concrete in Sodium Sulfate Solution

Abstract:

Article Preview

An investigation was carried out on the behavior of concrete under both sulfate attack and mechanical stress. The specimens of concrete with/without fly ash were subjected to flexural load with a level of 0.2 and 0.4 of their initial strength and also immersed into a 10% sodium sulfate solution or water respectively. The bending strength of the concrete was tested at certain time intervals. The results indicate that fly ash could effectively relieve the deterioration of the concrete in corrosive environment; flexural load could accelerate the corrosion damage and that the development of concrete strength is related to the internal structure, hydration product and the interface between coarse aggregate and cement paste.
