The Dimensioning of Adhesive-Bonded Joints in Concrete Building Components

In order to be able to predict the durability of adhesive-bonded (glued) joints made in concrete construction using epoxy resin adhesives, it is necessary to know the change undergone in the adhesion term under a variety of conditions. The first part of the present work thus deals with investigations of the performance and sustained load strength of adhesive-bonded joints under damp conditions and of the sustained load strength at increased temperatures, which were carried out by the author over a period of several years. On the basis of these results and of the results of investigations carried out by other authors a series of simple dimensioning equations are provided, taking the strength of the concrete into consideration. In addition to this, simple tests are suggested with which the suitability of epoxy resin mortars for adhesive-bonded joints in concrete construction can be checked.
