Durability Analysis of Adhesive Joints

The analysis of the quality of the adhesion of an epoxy material to concrete, or other materials, may be defined by the properties and thickness of a transition zone between the bulk adhesive and the pure adherend.Direct measurements of those properties and dimensions are very difficult without a strong interaction between the measurement technique and the obtained results. Mixed numerical experimental methods seems appropriate to obtain valuable information on the transition zone.A defined quality of adhesion on a test specimen can be compared with real adhesion by dynamic test methods.The influence of environmental factors on the quality of the adhesion are also measured on a test specimen and are the basis of a durability analysis of an adhesive joint taking into account classical dimensional analysis.
