Title (EN) METHOD OF REPAIRING/REINFORCING EXISTING STRUCTURES AND ANISOTROPIC WOVEN FABRICS USED THEREFOR
(FR) PROCEDE DE REPARATION OU DE RENFORCEMENT DE STRUCTURES EXISTANTES ET TISSUS ANISOTROPES UTILISES DANS CE BUT
Abstract:
(EN) A method of repairing/reinforcing existing structures such as buildings, in particular, concrete structures, which can be effected in a low-temperature environment and can exhibit excellent repairing/reinforcing effects in a short time. This method comprises the use of a fiber-reinforced resin layer prepared by impregnating a sheet made from reinforcing fibers with a resin and curing the resin, and the resin comprises a reactive mixture mainly composed of a vinylic monomer having a gelation time of 15 minutes or more at 25 °C and capable of being polymerized even at 5 °C and cured within six hours and a reactive vinylic oligomer and/or a thermoplastic polymer.
(FR) La présente invention concerne un procédé de réparation ou de renforcement de structures existantes, telles que des bâtiments, en particulier des structures en béton. Ce procédé peut être appliqué à basse température et fait preuve d'une efficacité de réparation ou de renforcement élevée en peu de temps. Il consiste à utiliser une couche de résine renforcée par des fibres, préparée par imprégnation d'une feuille de fibres de renforcement avec une résine qui est ensuite durcie. Elle comprend un mélange réactif, composé principalement d'un monomère vinylique ayant un temps de gélification de 15 minutes ou davantage à 25 °C, et capable d'être polymérisé même à 5 °C et durci dans les six heures, ainsi que d'un oligomère vinylique réactif ou d'un polymère thermoplastique, ou des deux à la fois.
