The science of adhesion is truly multi-disciplinary, demanding a consideration of concepts from such diverse topics as surface chemistry, polymer chemistry, rheology, stress analysis and fracture mechanics. On the other hand adhesives and bonding form a part of our everyday lives and there are very few of us who have not used ‘glues’ in one form or another for DIY jobs at home or work. The difficulty arises in translating an understanding of the complexities of adhesion science to some fundamental ground rules for achieving a strong and durable bonded joint which can be relied upon to transmit significant externally applied forces throughout the life of the structure or component. The construction industry, particularly the civil engineering side, presents a unique situation in respect of the conditions under which adhesive joints may have to be formed, the materials to be bonded and the relatively long design life required as compared with other industries such as aerospace and automotive.

The purpose of this book, therefore, is to provide the practising civil engineer with an insight into the factors involved in the formation of a successful adhesive joint, viz. adhesive selection, surface preparation, joint design, fabrication and protection from hostile conditions in service. The application of these principles is then illustrated by reference to examples of current uses in repair, strengthening and new construction, and the potential for future developments.
