  • Abstract Strengthening of concrete structures with externally bonded
    carbon-fiber-reinforced plastic (CFRP) materials appears to be a
    feasible way of increasing the load-carrying capacity and
    stiffness characteristics of existing structures. However, the
    lack of information about the adhesive behavior between CFRP and
    concrete has retarded the application of CFRP on the
    strengthening of concrete structures. Studies on the effects of
    environmental factors on the adhesive behavior as well as the
    failure mechanism of bond between CFRP and concrete are
    essential for development of the techniques. This study focuses
    on the adhesive behavior between epoxy-bonded CFRP and concrete
    through experiment. Surface treatment of substrate was done
    before the application of epoxy resin. Specimens were exposed to
    3 different temperature, 3 different relative humidity during
    curing age. In addition, the effect of different CFRP's length
    and number of sheet layers were investigated during experiment.
    Experimental results indicated that the effect of relative
    humidity on the adhesive strength between CFRP and concrete
    during curing age is insignificant. However, the adhesive
    strength of specimens decreased markedly with decreasing curing
    temperature. Increasing the length of CFRP proved to enhance the
    ultimate load of specimens, but reduces the overall average
    shear stress at failure. Increase in the number of sheet layers,
    on the other hand, enhances both the ultimate load and average
    shear stress of the specimens.
