Material Characterization of Composite Reinforced Mortars for the Retrofit of Masonry Walls
摘要
This paper discusses the effectiveness of Composite Reinforced Mortars (CRM) as seismic retrofit of existing stone masonry buildings through the material characterization tests carried out within the ERIES-RESTORING (REtrofitting of STOne masonRy using INnovative Grid-based composites) project. The mechanical contribution of these innovative strengthening materials, compatible with historical masonry, was assessed through vertical and diagonal compression tests. Three configurations were tested: bare undressed stone masonry, CRM applied to one side, and CRM applied to both sides. The tests were carried out on three specimens of each configuration. The experimental results are presented and discussed in terms of enhancement of elastic properties (Young’s and shear modulus) and compressive and tensile strength.
