ABSTRACT
Nowadays, the use of FRCM (Fabric Reinforced Cementitious Mortar) systems is largely adopted in the field of structural retrofitting. Nonetheless, the durability issue is a lightly investigated phenomenon, even if it is important for the long-term effects on external reinforcement effectiveness. This paper presents the results of freeze/thaw cycles and low temperature on the mechanical response of concrete members strengthened with a PBO-FRCM system consisting of Polyparaphenylenebenzo-bisoxazole fiber meshes embedded into an inorganic mortar. In particular, the experimental investigation was performed on small RC-beams (1000 mm long), on FRCM specimen and FRCM-concrete joints. Test results were reported and discussed in the paper.
