Abstract(s)The use of epoxies is today current in repair and bonding works of concrete structures. The raison of that is the good adhesion they present in bonding hardened concrete-hardened concrete, hardened concrete-fresh concrete and hardened concrete-metallic materials. However, the adhesion decreases when the substrate concrete is wet. The incorporation of a filler in the epoxy makes possible a good adhesion even when the concrete is wet. We did tension tests to study the influence of the type, the granulometry and the quantity of the filler on the behaviour of the bonds. Also the influence of the thickness of the joint is studied. The presentation of the results is made in accordance with a square optimisation method where is taken into consideration the adhesion in tension and the failure mode.
