“…The average bond strength is found to decrease with the increase in the bar diameter. This tendency agrees well with the results between CFRP/GFRP bars and concrete reported by other researchers [6,[22][23]. Compared with the 10-mm and 16-mm BFRP bars, the bond strength of the 4-mm bar is increased by 5% and 23.7%, respectively.…”

“…To evaluate the crack width and spacing and to understand the load transfer mechanism between FRP bar and concrete, various studies have been performed to evaluate the bond performance between carbon/glass FRP bar and concrete. It is concluded that the parameters such as the type of FRP bar, the bar surface, the bar diameter, the embedment length, the test setup and the concrete strength have a considerable effect on the bond behaviours [4][5][6][7][8].…”

“…However, few researches have been dedicated to shear connection systems for innovative structures like the FRP-concrete composite deck. Cho et al (2006) The perforated shear plate is a composite scheme making use of the concept of perfobond as a member achieved by monolithic fabrication of the FRP module at the top of the FRP member ( Fig. 2(b)).…”

Strong composition between FRP and concrete is an indispensable prerequisite to achieve the structural integrity of FRP-concrete composite deck. Accordingly, this study evaluates experimentally the behavioral characteristics of such shear connection systems realized by coarse sand coating and concrete wedge. The results show that coarse sand coating develops composite performance close to perfect composition in the shear direction but exhibits weakness against normal split. On the other hand, concrete wedge appears to be an efficient solution to resolve such problem. Therefore, a new shear connection system combining coarse sand coating and concrete wedge has been conceived and test revealed that the new shear connection system provides equivalent static performance together with significantly improved fatigue performance compared to the coarse sand coating composition. Following, the shear connection system combining both coarse sand coating and concrete wedge constitutes an efficient solution satisfying the strong composition requirement for the structural system.

“…The bonding performance between the small aggregates and FRP panel is subordinated to the bonding performance of epoxy whereas the gear performance between sand and concrete is influenced by the strength of concrete. Coarse sand coating exhibits optimal static performance when it is realized using sand with grain size of 4 -7 mm and density of 4 kg/m 2 [1]. In such case, the interface develops shear composition capacity close to perfect composition [2].…”

This paper examines the effect of freezing and thawing on the coarse sand coating chosen to achieve the composition of FRP and concrete in FRP-concrete composite deck. Push-out test specimens with dimensions of 100 × 100 × 450 mm were subjected to repeated freeze-thaw cycles under wet conditions ranging from −18˚C ± 2˚C to 4˚C ± 2˚C. The failure strength of the interface and the deformation of FRP at failure exhibited by the specimens that experienced 300 freezing-thawing cycles showed a difference of merely 5% compared to those of the specimens that were not subjected to freeze-thaw. This indicates that coarse sand coating is not affected by freezing-thawing cycles and the FRP-concrete composite deck owns sufficient applicability in terms of durability against freezing-thawing.
