Abstract: Strengthening of masonry structures through sustainable materials, compatible with the substrate, is gaining an increasing interest in the academic as well as professional world.As known, a large part of the historical building heritage consists of masonry buildings characterized by heterogeneous structural arrangements, highly vulnerable in case of seismic events.Furthermore, these buildings were often built without accordance to any regulations in terms of energy efficiency.In the last two decades, TRM (Textile-Reinforced Mortar) composites were widely used to improve the structural behavior of buildings and a large number of data are available in the scientific literature concerning composite materials assembled with different types of textile and matrix.FRLM (Fibre-Reinforced Lime Mortar) composite used in this research was assembled embedding a basalt textile in a properly selected thermal mortar with the goal of an integrated energy and seismic upgrade of masonry buildings belonging to historical heritage.In particular, 100 lime-based thermal matrices available in the context of the European market were selected to identify those with the best energy and mechanical properties in order to create an innovative, eco-sustainable and eco-compatible latest-generation composite material that combines good energy as well as mechanical performances.The behavior of such assembled composite material while applied on masonry structures was experimentally investigated at the Laboratory for Testing Materials and Structures of the University of Florence through bond test and diagonal compression test.This investigation highlighted promising results in terms of bond performance of such innovative composite and shear strength of strengthened masonry structures even if wider experimental campaigns and properly defined numerical assessments are necessary to confirm these data and to allow more general conclusions useful for both academic field and engineering practice.
