ABSTRACT
This chapter outlines the results of masonry walls strengthened with two inorganic matrix-composite grid systems made of glass and hemp fibers. The complete experimental program concerns diagonal compression tests carried out on a total of 50 unstrengthened and strengthened masonry walls made of both tuff blocks and clay bricks. FRPs have been proposed in combination with inorganic matrices for structural retrofit of existing masonry structures as they are able to guarantee high mechanical and physical compatibility with the existing walls. Innovative technologies and materials have been considered in order to maximize the physical and mechanical compatibility with the existing masonry structures and to achieve economic and environmental benefits. The overall experimental results showed a remarkable improvement of mechanical performances of the masonry walls in terms of both strength and ductility in all the strengthening configurations. The experimental program consisted in diagonal compression tests carried out on 50 masonry walls made of Neapolitan yellow tuff and clay bricks.
