The bond between fabric reinforced cementitious matrix (FRCM) and masonry substrates is investigated in this paper. An experimental investigation was performed on eighteen clay brick specimens strengthened with a single layer of carbon FRCM (CFRCM). Direct shear tests (single lap) were conducted at an ambient temperature of 20°C varying the bond length of the CFRCM reinforcement [Lb ¼ 150 ð6Þ, 200 (8), 250 (10), and 300 (12) mm (in.)]. Experimental bond strength values, bond-slip law, and failure modes described and analyzed in this paper allow for evidencing of the bond performances of the CFRCM-masonry substrates. Finally, an analytical local bondslip law was defined and used to compare theoretical predictions and experimental results.

Abstract
The bond between fabric reinforced cementitious matrix (FRCM) and masonry substrates is investigated in this paper. An experimental investigation was performed on eighteen clay brick specimens strengthened with a single layer of carbon FRCM (CFRCM). Direct shear tests (single lap) were conducted at an ambient temperature of 20°C varying the bond length of the CFRCM reinforcement [Lb ¼ 150 ð6Þ, 200 (8), 250 (10), and 300 (12) mm (in.)]. Experimental bond strength values, bond-slip law, and failure modes described and analyzed in this paper allow for evidencing of the bond performances of the CFRCM-masonry substrates. Finally, an analytical local bondslip law was defined and used to compare theoretical predictions and experimental results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
