Abstract:
Describing concrete behavior, Fred Goodwin proclaimed: “concrete cracks, you have to deal with it!” Cracks in concrete structures are a primary path for the ingress of water, chlorides, and other deleterious materials. In repaired structures, cracks are also a potential indication of debonding of the repair material from the substrate. The long-term durability of a repair is heavily influenced by how the repair design accommodates the potential for cracking. The cracking sensitivity in repair materials is influenced by many factors, with dimensional incompatibility adversely affecting the load-carrying capacity and durability of repaired elements. The presentation will provide guidelines to achieve dimensional compatibility of repairs and minimize the impact of cracking on repaired structure durability.
