Evaluation of Adhesive Strength of Resin Liner Film

Abstract

In this study, a new method for evaluating the adhesive strength of the interface between resin liner film and cement mortar has been developed. The peel test for vinyl ester resin liner films on cement mortar surfaces was carried out. The critical energy release rate (G c value) was obtained from the peel load and crack length measured during the peel test. G c values were not affected by the crack length or the thickness of resin liner film. Therefore it was established that G c values could be used to evaluate the adhesive strength of resin liner film. Furthermore, the effect of primer coats on the adhesive strength of resin liner film was revealed by obtaining the G c values.
