Effect of contact pressure on bond strength of fiber-reinforced polymer to concrete

Xiong, G.J. / Ma, X. / Ji, Z.

In this technical note, the importance of contact pressure (0.03 N/mm²) during curing of adhesive between fiber reinforced polymer (FRP) and concrete is addressed. The shortcoming of fast-curing epoxy resin is pointed out. Different pressures and an ordinary epoxy resin were chosen to assess the effectiveness of contact pressure on FRP-to-concrete bond strength. The test results showed that the bond quality could be significantly improved by exerting a contact pressure >=0.01 N/mm². A simple and easy site-operation method for exerting contact pressure is also introduced.
