A New Compatible and Sustainable FRLM Composite for the Seismic and Energetic Upgrade of Historic Buildings

The historic building heritage’s energy and structural requalification is a crucial topic usually investigated by separate approaches and procedures. This paper covers an integrated assessment of a new composite material to reduce the seismic vulnerability of historic masonry buildings while complying with the requirements of sustainable conservation, reduction of emissions, and energy saving. Firstly, research and selection of thermal mortars to be used as the matrix of the innovative composite material were carried out; then, the mechanical properties were investigated through compressive and bending tests. Furthermore, the mortar with better mechanical properties was used to assemble a composite specimen under the direct tensile test. Finally, dynamic thermohydrometric simulations by WUFI ® Pro software and EnergyPlus software were performed to check energetic contributions when applied on typically arranged masonry panels of existing masonry buildings.
