Sulfate Attack of Bridges

Engineers have traditionally considered sulfate attack on concrete structures as an underground problem. However, recent investigative work has amassed considerable evidence of sulfate attack on the above ground components of concrete structures. This paper reviews findings of a research project with respect to the prevalence of attack, its extent, and the identification of structures at risk. Improvements identifying sulfate attack are discussed and performance of sulfate resisting and blended cements is reviewed. Relevant reviews are presented from the United Kingdom, Ireland, and the United States that demonstrate that sulfate attack of above ground components of highway structures is more widespread than previously thought, sometimes as a result of lack of diagnosis/misdiagnosis.
