ULTRA-HIGH PERFORMANCE PLASTER (UHPPl) FOR SEISMIC REINFORCEMENT OF MASONRY WALLS

This work presents the preliminary results for a retrofitting technique to use on the seismic reinforcement of ancient structures (buildings and others). The technique involves the replacement of masonry walls exterior or interior plasters or renders, with a retrofitting material that will significantly enhance the out-of-plane and in-plane mechanical behaviour of such walls, with major significance for the seismic response of the intervened structure. The reinforcement material (UHPPl) must respect the physical features and traits of the substratum in which it will be applied, as also its mechanical characteristics have the specific need to be consistent with the same substratum.
