Abstract

The combined application of Carbon Fiber Reinforced Polymer (CFRP) and recycled aggregate concrete is of great importance in conserving resources and reducing environmental pollution. A dynamic experimental study was conducted using a double-sided shear test method, and the bonding behavior of CFRP sheet-recycled aggregate concrete interface was analyzed. The effects of seven kinds of bond length, four kinds of bond width and three kinds of load rate on the interface properties were considered. The experimental results demonstrate that: 1) The main damage pattern of the CFRP sheet-recycled aggregate concrete interface is stripping damage of concrete surfaces. 2) As the bond length and bond width increase, the ultimate bearing capacity of the CFRP sheet-recycled aggregate concrete interface increases, and the influence of loading rate on the ultimate bearing capacity decreases. 3) It is evident that the interfacial fracture energy and interfacial shear stress are subject to a pronounced strain rate effect. In the bond-slip relationship of the interface, a reduction in bond width and an increase in loading rate result in an increase in the slip corresponding to the peak shear stress.
