Bond Behavior of Aluminum Laminates in NSM Technique

Abstract:

An attempt was made to replace the commonly used Fiber Reinforced Polymer (FRP) with aluminium alloy in NSM technique. This paper presents experimental investigation of interfacial bond behavior between NSM aluminium laminates and concrete structures. Aluminum laminates were mounted into premade slit of concrete with epoxy resin. Test results show that both maximum applied force and ductility of NSM reinforced specimens can be effectively improved by increasing bond length and width of aluminium laminates, whilst almost no change was found in average bond strength at the same time. Besides, the loaded end slip of specimen, corresponding to the maximum applied force, was mutually influenced by bond length and width of aluminium laminates. Furthermore, the measured strain distribution of aluminium laminates along the direction of bond length of specimen was found to be similar to that of FRP in NSM technique.
