Abstract:This paper describes the bending behavior of advanced laminated cementitious composites reinforced with FRP meshes embedded in a cement mortar matrix with or without discontinuous fibers. When fibers are added the term hybrid laminated composite is used. Three different types of meshes (Kevlar, Spectra and carbon) were used in combination with three different discontinuous fibers, two PVA fibers and one carbon fiber. Since previous investigations by Naaman and Guerrero (1996) have indicated that the com-bined use of two layers of mesh reinforcement and discontinuous fibers gives a cost optimum combination for bending response, only two layers of mesh reinforcement, placed near each extreme surface of the specimen, were used in this study. The specimens were tested in four point bending. The loads and midspan deflections were measured. Equivalent elastic bending stress versus deflection curves are generated and representative curves are used to com-pare the first cracking strength, the post-cracking behavior, the maximum post-cracking strength or modulus of rupture, the unidirectional cyclic behavior and the toughness indexes.
