Laboratory and Field Evaluations of External Sulfate Attack in Concrete
Sulfate attack is a complex form of deterioration that has damaged concrete structures throughout the world. Sulfate attack is particularly complex because the source of sulfates can be external or internal (delayed ettringite formation), and the distress can be chemical in nature, due to alteration of hydration of products, or physical in nature, due to phase changes in the penetrating sulfate solution. Although sulfate attack has been recognized as a cause of concrete distress for many years, it remains a controversial, confusing, and complex topic. There are many unresolved issues, far too many to be tackled in a single investigation. The research described in this report aims to address several of these lingering issues, especially those that are particularly relevant to the state of Texas.
