Experimental Investigation of Continuous Shear Bonding Field in Ferrocement-Aluminium Composite Elements

Bonding between various construction materials is the key to developing smart composite action within structural elements, likewise beams, slabs, columns, etc. The push-out test is best to determine shear bonding strength and related slip and uplift response in composite components. Push-out test almost could be considered a smart, efficient technique to predict the shear bonding strength between various construction materials in the laboratory. There is no code specification related to the push-out test for adhesive shear bonding. This study introduces a suggested mode regarding continuous shear bonding field in concrete-metal composite elements, which adopts the most common configuration considered in investigating the mechanical fastener's shear resistance. An experimental program is considered. The results depict that the failure loads are changed from (55.7 kN) to (58.01 kN) as the thickness of the adhesive epoxy layer increased from 3 mm to 6 mm, and the results related to the behaviour of load - slip an exponential equation normalizes response of adhesive epoxy layer. Generally, the obtained results confirmed that the introduced continuous shear bonding field could be considered a more proper technique than the mechanical technique. The slip remains very small during the test.
