The compatibility between new and original elements of masonry buildings is an essential aspect of the intervention effectiveness for seismic rehabilitation. In particular, the structural and mechanical compatibility of the element that has to be strengthened must be characterized mechanically, in order to intervene with a proper material. In this paper former results obtained within the framework of a widely applicable research program dealing with the rehabilitation of masonry panels characterized by elements of different mechanical performance, are reported. These results are related to the use of two types of mortars: a non-structural kind, containing polypropylene fibres, and a structural one, reinforced with a Kevlar textile grid. The masonry blocks were subjected to either axial or diagonal compression tests. Results obtained show a generally appreciable strength improvement under axial compression, while a significant improvement was obtained with the structural mortar under diagonal compression test.
