Bond and tensile behaviour of textile reinforced mortars with traditional and alternative matrices
Reinforced and prestressed concrete structures frequently need to be repaired and strengthened during their service life due to corrosion deterioration and other pathologies. Composite materials, such as textile reinforced mortar (TRM), have emerged as a promising solution for restoring or improving the load bearing capacity of structural concrete. Previous studies have demonstrated that the effectiveness of this strengthening technique relies mostly on the bond between the textile and the matrix as well as on the bonded length to the substrate. The research presented in this paper aims to evaluate the efficiency of bond characteristics as well as the mechanical properties of various TRM systems. Carbon and basalt textiles were investigated along with conventional cement mortar and alternative mortars with short glass or synthetic fibres. To examine the bond behaviour of each system, a single lap shear test configuration was used. Tensile testing was carried out using a clevis grip or a clamping configuration. The tension and bond properties obtained from the tests are analysed and compared, and recommendations are presented regarding the bond and tensile test setups. ; The study presented in this paper was developed in the scope of research project PID2021-123701OB-C21 funded by the Spanish Ministry of Science and Innovation (MCIN/AEI/10.13039/501100011033/) and the European Regional Development Funds (ERDF) as well as research project TED2021-130272B-C21 funded by the Spanish Ministry of Science and Innovation (MCIN/AEI/10.13039/501100011033) and the European Union NextGenerationEU/ PRTR. The first author would like to acknowledge the FI SDUR scholarship program for their invaluable support. The authors would also like to acknowledge the dedicated LATEM laboratory staff of the UPC, whose expertise and assistance were important throughout the experimental campaign. Additionally, the authors would like to thank Mapei and their employees, for their courtesy supplying required materials and giving technical ...
