Behavior of thin masonry arches repaired using composite materials

Characterization tests of GFRM coating as a strengthening technique for masonry buildings

“…The durability behavior of the GFRP grids exposed to various environmental conditions was investigated by Corradi et al [14]. The effectiveness of the technique in the seismic enhancement of masonry walls (inplane and out-of-plane) and vaults was investigated [15][16][17][18]; in these studies the importance of a good bond between the reinforcement and the masonry substrate and between the mesh and the mortar matrix emerged.…”

Seismic retrofit of historical masonry walls by means of natural basalt fiber strips system (BFRP). Pre-modern concepts and innovative materials

“…On the efficacy and potential for use of innovative materials such as FRP or UHTSS, high strength stainless steels, applied in the form of a grid (Reticulatus System) in the field of seismic retrofit of masonry walls belonging to historical buildings, it has been widely written in the specific scientific literature [20][21][22][23][24][25][26][27]. The traditional timber frame reinforcements can be effectively replaced by a homologous frame, according to a similar geometric pattern, composed of natural basalt fiber strips, arranged in adherence to the wall front and glued to the wall itself by means of a GeoCalce (a KeraKoll patent), a hydraulic lime matrix compatible with the traditional binder present in the walls (Fig.…”

An experimental study on the influence of composite materials used to reinforce masonry ring beams

“…Recently researchers have focused their interest on the use of composite materials coupled with non-polymeric matrixes [9][10][11][12][13][14], like lime-based mortars [15][16][17][18] with the aim at increasing the durability [19][20]. The aim is to avoid the use of epoxy or other polymeric resins, due to their critical long-term behavior.…”
