Résumé / Abstract
The gluing technique is a promising asssembling method in civil engineering, since it opens new horizons in the design of complex concrete or steel structures. However, at the present time, several breaks are slowing down its industrial development : its is a delicate technique which requires a qualified staff in order to respect baseic rules of implementation ; recurrent interrogations concerning the long-term durability of adhesively bonded joints are still not answered. A physical-chemical approach of the problem may provide elements of solution. The first part of this article propose some rules of implementation derived from physical-chemical considerations, which are necessary to ensure safety of the adhesive bond. In the second part, experimental results are presented, giving an improved description of the microstructure of bonded joints. These results illustrate the interest of a physical-chemical study for the identification of parameters susceptible to govern mechanical strength and durability of the adhesive bond.
