Description
In the context of wall consolidation of historic or monumental buildings, there is an increasing demand to use strengthening techniques that involve eco-friendly materials. FRCM (Fibre Reinforced Cementitious Matrix) systems are widely used in the static and seismic rehabilitation of existing Italian buildings, in particular for the reinforcement of masonry structures. They consist in the creation of reinforced plasters (inorganic matrix mortar) with thicknesses between 5 and 15 mm through the interposition of structural mesh made up by different materials such as high resistance steel, aramid, basalt, carbon, AR glass. The qualification of the systems in Italy can take place according to the Guideline of the Ministry of Infrastructure and Transport which defines the characteristics of the components, the requirements and the test methods to follow to establish the performance of the FRCM systems. The present work has placed in this context, illustrating the results achieved by an experimentation with new reinforcement mesh, made up of interwoven natural fibers that come from pure plant origin, combined with lime-based structural mortars typically used in historical field. The system and the mesh have been characterized by some mechanical properties according to the Italian Guideline for the technical qualification of FRCM.
