Study on the Sulfate Corrosion of Concrete under the Action of Loading

Abstract:

In this paper, the sulfate resistance properties of concrete under loading action are studied. The concrete specimens with different water/cement ratio are prepared and correlative corrosive experiments are carried out under single damage factor (SDF) and multiple damage factors (MDF), which is relative with drying and wetting cycles. Dynamic elastic modulus is taken to characteristic the sulfate resistance properties of concrete under the action of loading, drying and wetting cycles and sulfate corrosion. Results show the corrosion mechanisms of sulfate attack due to single damage factor and multiple damage factors were not all the same, and multiple damage factors could indicate the concrete structure due to sulfate attack more exactly.
