Evaluation of Bonding Agent Application on Concrete Patch Performance

Concrete patching is a commonly used infrastructure preservation and repair technique. Patches are used frequently in the U.S. Midwest to repair areas of concrete freezing and thawing joint distress. The repair patches usually fail first at the interface between old and new concrete. Bonding agents such as cementitious grout or epoxy are often specified to enhance the bond. There is concern that these bonding agents may be more sensitive to environmental and construction practices than previously thought and that these bonding agents may actually give poor performance in the field. This project will establish the sensitivity of bonding agent performance to environmental and construction practices, and provides recommendations for achieving optimum performance. This will be accomplished by testing the repair bond to concrete for cementitious and epoxy bonding agents subject to different drying times. The repair will be also cycled through five temperature cycles before testing the bond using the guillotine test. Field trials will also be used to confirm the material sensitivity determined through the laboratory testing.
