Abstract

This paper seeks to demonstrate how advanced composite materials as F.R.C.M. (fiber reinforced cementicius matrix) can offer high advantages for repairing ageing infrastructures. The FRCM strengthening system can be considered alternative to the well-known fibre-reinforced polymers (FRP) system; the FRCM system, in fact, permits the elimination of some disadvantages related to the use of organic resin such as lack of fire resistance and low compatibility with the concrete substrate. In this study, a data comparison between non-reinforced and reinforced models is discussed. The specimens simulated a part of a bridge deck to repaiur or strengthen. The samples were no. 6 plates 70x70 cm ² long and 10 cm thick realized by a mix design concrete [1] of 30/35 class and reinforced by steel bars. The strengthening system consists in applying the composite biaxial sheet at the intrados of the deck in two layers orthogonal each other.
