Evaluation of fiberglass wrapped concrete bridge columns

Abstract

The main purpose of this project was to assess the effectiveness of fiberglass wrappings in reducing the corrosion degradation rate of concrete bridge columns. To evaluate the effectiveness of the technique, the research team used both nondestructive and destructive test methods. The results of the study show that the wrappings, while protecting the columns from further ingress of chloride ions, do not help deter corrosion activity when it is already present. Recommendations for the future use of fiber wraps, complemented with other remediation techniques and maintenance practices, are provided.
