Abstract
In this paper, we developed a new method for evaluating the adhesive strength of paint film on a concrete surface. The peel test for paint film was carried out. A reinforcement plate was attached to the paint film so that it would not be damaged during the peel test. The critical energy release rate (Gc value) was obtained by using peel load and the displacement of the loading point measured during the peel test. Gc values were not affected by the thickness of the reinforcement plate and the peel length. Therefore, it was clear that Gc values could be used to evaluate the adhesive strength of the paint film. Furthermore, the influence of the environment on paint films was elucidated by obtaining the Gc value.
