ABSTRACT

In the recent years, several applications with cement-based matrix have been proposed but the effective mechanical properties of the bond between masonry and reinforcement has not been carefully investigated. Most of approaches have been devoted to reinforced concrete rather than masonry structures. In Huang et al. (2005), steel reinforced grout (SRG) has been considered for strengthening reinforced concrete beams, through an experimental investigation on specimens under four point bending. In Di Tommaso et al. (2007) an experimental investigation on reinforced concrete beams under flexure, was undertaken to compare the performances of C-FRP and C-FRCM. Bond-slip tests of SRG sheets applied to concrete specimens have been carried out in Matana et al. (2005). Similar tests on brick specimens reinforced with FRP have been undertaken in Briccoli Bati (2007), aiming at investigating the effective bond length. However, an experimental campaign on the performances of bond in cement-based matrix is still lacking.
