Ultrasonic Pulse Velocity Evaluation of the Pull-Off Adhesion between Epoxy Resin and Concrete Substrate

Abstract:

Adhesion assessment between epoxy resin and concrete substrate is described in the article. Two-layered cylindrical elements were obtained from the borehole in the object created for the purpose of the test. Adhesion analysis has been performed for two groups of elements of different composition. The ultrasonic pulse velocity (UPV) method with two-sided access was used to assess the adhesion. Pull-off adhesion f_b compared with the ultrasonic wave velocity V has been determined. Relationships between the ultrasonic wave velocity V and pull-off adhesion f_b, obtained with the semi-destructive pull-off method, were determined for both groups of elements. It was proved that together with an increase on the elements of the ultrasonic velocity wave V, the pull-off adhesion value f_b between the epoxy resin and the concrete substrate also increases.
