THE EFFECTS OF ENVIRONMENTAL FACTORS AND SUSTAINED LOAD ON THE BONDING PERFORMANCE BETWEEN CFRP AND CONCRETE
The influence of environment and sustained load were considered to study the bonding performance between the CFRP composites and the concrete member based on the accelerated aging tests. It is shown that the effects of environment and sustained loads accelerate the degradation of bonding performance in the interface of CFRP sheets and concrete member. Higher bonding stress and micro-cracks occurred on the interface due to the sustained load accelerate the diffusion process of corrosion ions,which speed up the degradation of resin layer,and consequently vary the failure mode.
