Structural and patch repair in concrete structures

Maintaining and repairing building stock has been a recurring need owing to the natural degradation of materials and structures under the combined effects of loads and environmental factors. The urgent need to repair structures that have failed ? because they either were not designed to withstand service conditions or were not properly constructed? has made durability the most pressing construction problem of the day.La maintenance et la r\ue9fection du patrimoine b\ue2ti repr\ue9sentent un besoin r\ue9current en raison de la d\ue9gradation naturelle des mat\ue9riaux et des structures sous l?action combin\ue9e des charges et des facteurs environnementaux. En raison du besoin imp\ue9ratif de r\ue9parer les structures d\ue9faillantes, soit parce qu?elles n?ont pas \ue9t\ue9 con\ue7ues en fonction des conditions de service effectives, soit parce qu?elles n?ont pas \ue9t\ue9 construites ad\ue9quatement, la durabilit\ue9 est devenue le probl\ue8me de construction le plus urgent.Peer reviewed: YesNRC publication: Ye
