“…Moreover, severe steel corrosion problems emerged in several cases, over the time. For this reason, traditional retrofitting techniques were gradually replaced, in the last twenty years, by different reinforcement solutions based on no-corrosive materials such as FRP, based mostly on carbon, glass or aramid fibers [12,13], PBO (polybenzoxazole) [14], PP (polypropylene) [15] or stainless steel [16,17]. The fundamental benefits of the reinforcement with a composite material are strictly related to its great performances when subjected in tension.…”

“…Equation (14) assumes that the ASFRM overlay does not fail after the peak load is reached. However, diagonal cracks were formed on the ASFRM overlay at the peak load in the case of concrete brick masonry strengthened on both sides.…”

“…The average ratios of the test strength over the nominal strength were 1.15 and 1.12 for the strengthened masonry prisms in red clay bricks and concrete bricks, respectively. Hence, Equation (14) underestimates the diagonal strength conservatively. The effect of filling the vertical joint partially when plastering the ASFRM might have contributed to the underestimation of the diagonal tension strength; this is because S m in Equation ( 14) is based on the strength obtained from specimens with weak vertical mortar joints.…”

A technique for strengthening masonry walls by plastering with amorphous steel fiber-reinforced mortar (ASFRM) is investigated through compressive and diagonal tension tests for masonry prisms. The vertical joint between masonry units was not completely filled with mortar to mimic poor workmanship, which is typically reflected in low-cost buildings. The test variables include the number and thickness of mortar overlays, fiber volume fraction, and additional reinforcement using glass fiber mesh or shear connectors. In most strengthened specimens, the ASFRM is not damaged but separated from the masonry prisms after its maximum strength is reached. Additional tests for the bond strength between the ASFRM overlay and masonry surface are conducted to evaluate its contribution to the strengthening effects. Based on experimental observations, equations for predicting the compressive and diagonal tension strengths of masonry prisms strengthened with ASFRM are proposed. The compressive strength can be predicted more accurately by considering the asymmetrical distribution of compressive stress when strengthening is performed on only one side. The diagonal tension strength after strengthening can be predicted by incorporating the contribution of the bond strength between the ASFRM overlay and masonry prism to the initial strength.

“…By suppressing crack development and/or crack progress, the failure of the masonry walls may be prevented [1]. There are various techniques to prevent crack progress by retrofitting masonry with ductile materials and there are many studies performed about these techniques, few resent ones are sited here [2][3][4][5][6]. One of the methods is to plaster the masonry wall by fibrous cementitious material.…”
