In-situ Pull-off Tests
Length: 49 Minutes
This session will describe the use of tensile pull-off (bond) testing for concrete repairs and bonded overlays. It will provide guidance on applications of the test, industry standards and guidelines, acceptance criteria, proper testing procedures, appropriate equipment, and interpretation and reporting of test results. Bond is important because it relates to structural requirements (e.g. for strengthening and structural repairs) and for durability requirements (e.g. for overlays and cosmetic repairs). Testing of bond is needed to verify that the specified bond requirements have been met and a satisfactory result has been obtained.
