Et al. [24] and De Munck et al. [25], which exposed AR glass TRCs to 2500 and 100 freeze haw cycles, respectively. Research dedicated to investigating the durability from the bond in between inorganic-matrix reinforcement and specific substrates are very limited. Donnini et al. [2] exposed AR glass FRCM-masonry joints to ten wet ry cycles in saline remedy and observed a 20 reduction in their peak tension. In addition, the failure mode was shifted from the matrix iber interface to the matrix ubstrate interface. Franzoni et al. [1] observed a 16.3 reduction of peak anxiety of SRG-masonry joints subjected to six wet ry cycles in saline answer, whilst a 12 reduction was obtained when the same cycles have been performed in deionized water. The results readily available inside the literature does not let for identifying a clear trend regarding the impact of various environmental exposures and accelerated aging. In addition, the limited info on the long-term bond behavior of FRCM, SRG, and CRM systems may well limit their utilization or force to make use of pretty severe environmental conversion components [26]. Within this paper, the long-term bond behavior of inorganic-matrix reinforcements is investigated by exposing FRCM-, SRG-, and Nimbolide custom synthesis CRM-masonry joints to 50 wet ry cycles then testing them using a single-lap direct shear test set-up. The FRCM composites comprised carbon, PBO, and AR glass textiles embedded within cement-based matrices, although the CRM and SRG comprised an AR glass composite grid and unidirectional steel cords, respectively, embedded inside precisely the same lime mortar. The exposure situation was designed to simulate a 25-year-long service life of externally bonded reinforcements that were totally soaked twice a year. This situation might be representative with the intrados ofMaterials 2021, 14,3 ofbridges subjected to cyclic floods [27]. The outcomes obtained have been compared with those of nominally equal unconditioned specimens previously tested by the authors [11,28]. two. Experimental Plan In this study, 5 inorganic-matrix reinforcement systems were studied, namely a carbon FRCM, a PBO FRCM, an AR glass FRCM, an SRG, and an AR glass composite grid CRM. Six specimens were prepared for every single type of reinforcement and were all subjected to wet ry cycles prior to testing. Nominally equal unconditioned specimens had been presented and discussed in [11,28] and are regarded here for comparison. Specimens presented within this paper were named following the notation DS_X_Y_M_W/D_n, where DS could be the test kind (=direct shear), X and Y indicate the length and width in the composite strip in mm, respectively, M could be the reinforcement kind (C = carbon, P = PBO, G = AR glass, S = SRG, and CRM = composite-reinforced mortar), W/D (=wet/dry) indicates the conditioning, and n may be the specimen quantity. two.1. Materials and Approaches In this section, the main physical and mechanical properties on the matrix and reinforcement used are offered. Though these properties do not enable for directly obtaining Ethyl Vanillate site indications around the matrix iber interaction, they are basic to understand the reinforcing technique behavior and its failure mode. Table 1 reports the key geometrical and mechanical properties of the fiber reinforcements and matrices utilised in the 5 systems investigated. In Table 1, bf , tf , and Af will be the width, thickness, and cross-sectional area of a single bundle (also referred to as yarn) along the warp path, respectively. For steel cords and AR glass bundles, which are idealized wi.
