Field tests were carried out to investigate the bond behaviour of Steel Reinforced Grout (SRG) systems, making use of Ultra High Tensile Strength Steel cords embedded into a lime based mortar, bonded to the extrados of masonry vaults. Test outcomes provided the SRG-to-substrate shear bond strength after the development of a crack at the extrados of the vault. The incidence of the curvature, of the heterogeneity of the substrate and of the actual site conditions related to substrate preparation and mortar curing are discussed.
