Pull-Off Adhesion Strength Testing of Lining Systems on Concrete: A Review of the Various Direct Tensil Test Methods Used for Severe Service

Pull-Off Adhesion Strength Testing of Lining Systems on Concrete: A Review of the Various Direct Tensil Test Methods Used for Severe Service
Available for download

Tensile pull-off adhesion testing is becoming a more frequent specification requirement for in situ quality assurance testing to confirm proper surface preparation and adhesion of high performance protective linings applied to concrete. It is also becoming a widely used test for forensic analysis of protective linings in existing installations. There have been numerous investigations leading to the development of different devices and test pull-off adhesion methods used to assess bond strengths of mortars and overlay materials

Tensile pull-off adhesion testing is becoming a more frequent specification requirement for in situ quality assurance testing to confirm proper surface preparation and adhesion of high performance protective linings applied to concrete. It is also becoming a widely used test for forensic analysis of protective linings in existing installations. There have been numerous investigations leading to the development of different devices and test pull-off adhesion methods used to assess bond strengths of mortars and overlay materials. There are fundamental differences between these methods that can dramatically impact tensile strength results. This paper presents the common pull-off adhesion test methods used in the United States as well as the results of experimental research investigating the results using two common tensile strength testers.

Pull-off adhesion testing is widely used to assess the protective coating process. It is also used to determine if a coating is fit for service in new construction and for repairs to existing structures. The result is often critical to the acceptance or rejection of a coating process, as the adhesion value quoted by the paint manufacturer can be adversely affected by aspects of the coating process. Low adhesion values are indicative of premature failure of the coating and are often due to inadequate surface preparation of the substrate.

A long-term project such as the current Brooklyn Bridge Rehabilitation Program, known as Brooklyn Bridge Contract 6, presents a great opportunity to collect vast amounts of data and records relating to the total coating replacement on a historic landmark. On any project, especially one of this scope, the project team has to deal with many obstacles, both expected and unexpected, and significant unknowns.

Pull-off adhesion testing of coatings is commonly used for product testing and qualification as well as quality control / quality assurance. However, initial adhesion values do not necessarily correlate with service life of coatings or their corrosion protection performance. Adhesion of several product chemistries to steel is examined in this study before and after immersion exposure. Results are presented within the context of laboratory corrosion testing in an effort to investigate the significance of adhesion testing in modern lining systems.
