Effect of Surface Treatment and Test Configuration on Bond Behaviour of GFRP Rebars

Popis výsledku v původním jazyce

This paper deals with the determination of the effect of surface treatment and test configuration on the bond behaviour of GFRP reinforcement embedded in concrete. Several types of tests were performed, such as centric pull-out tests, modified pull-out tests, and beam tests to obtain the bond properties of bars with different surface treatments. The sand-coated bars exhibited different bond behaviour compared to the ribbed ones due to different forces transferred from the reinforcement to the concrete. This paper also focuses on the determination of the effect of alkaline environment degradation on the efficiency of sand-coated bars. It is well-known that test configuration affects bond behaviour, however, this effect was not sufficiently quantified until now. A modified beam-bending test to assess the bond performance is presented in this study. The results of an experimental study comparing the bond performance of GFRP bars with different surface treatments obtained from the beam tests and centric and modified pull-out tests are presented.
