Test on Corrosion Resistance of GFRP Anchor Bolt

Steel is commonly used as the materials of anchor bolts in permanent anchoring works. The nature the steel anchor bolt easy to be corroded, however, poses a serious potential safety hazard to the anchoring system mainly including steel anchor bolts. To use GFRP(glass fiber reinforced polymer) anchor bolts instead of reinforcing bars is an effective means to deal with corrosion.
