摘要：

The detachment of ceramic tiles in buildings is a problem that still persists in several modern constructions, despite various advances achieved. In this work, the adhesion resistance was evaluated from the crack propagation test in a mixed mode of stress (MMF test), which simulates tensile and shear forces simultaneously. A punctual progressive load was applied to 120 specimens in order to evaluate the influence of several variables: type of adhesive mortar, mortar thickness and failure extension. The results show that the bonding strength at the interface decreases as the adhesive failure increases. The bonding strength values found by the direct-drive test were higher than the results obtained by the MMF test, indicating an overestimation. (C) 2020 Elsevier Ltd. All rights reserved.
