Abstract:The usual method of strengthening concrete structures with fiber reinforced plastic (FRP) is to bond FRP sheets on the surface of concrete, so the bond strength between concrete and FRP sheets is a key issue which affects strengthening. The effect of environment on FRP strengthening concrete structures is related to the bond surface of FRP and concrete. Experiments show that the bond strength between concrete and FRP sheets decreases under the freeze-thaw conditions.
