Reliability of Different Test Setups and Influence of Mortar Mixture on the Fabric-Reinforced Cementitious Matrix-to-Brick Bond Response

What is it about?

In this paper the influence of bond test set-up on the bond response of Basalt-FRCM composites used for strengthening masonry structures is investigated. Bond tests are fundamental to investigate the capability of different layers/materials (in this case fiber-to-matrix and composite-to-support) to maintain a good adhesion between each other. It is crucial in case of composite materials, i.e. materials made of different components. As in literature different tests are available and corresponding results highlight an high variability, this paper aims at compare the results of four types of bond test - 1) single-shear test on a brick unit, 2) double-shear test on a brick unit, 3) double-shear test on a system of two brick units; 4) beam test on a system of two brick units reinforced at the intrados - in order to investigate the influence of the bond test typology. The results involve both the research field and the engineering practical applications.
