Bond Behavior Between Glass Fiber-Reinforced Polymer (GFRP) Bars and Saline Water–Sand Concrete
This paper presents an experimental study to investigate the bonding behaviour between GFRP bars and the concrete made from saline water and sand. The experimental program included twenty-four specimens of the concrete made from saline water and sand as an experimental group and six specimens of common concrete as a control group. The major survey parameters include the compressive strength of concrete (25 MPa and 35 MPa) and the diameter of GFRP reinforcing bar (12 mm and 16 mm). The specimens are examined under the pull-out testing method. The research results show that the average bonding strength of GFRP bars in the concrete made of salt-contaminated water and sand has only slightly been decreased from 5.6 to 7.2% compared to that in fresh water- sand concrete, and the decline degree of this bonding strength in 12 mm-diameter GFRP bars is more obvious than that in the 16 mm- diameter bars. The increase of concrete strength from 29.28 MPa to 35.56 MPa significantly enhances the average bonding strength of the 12 mm GFRP bar (18.7%), but only a slight improvement has been recorded in the 16 mm GFRP (6.3%). Increasing the GFRP bar diameter from 12 to 16 mm boosts the average bonding strength from 11.7 to 35.4%.
