GFRP-tube confined RAC under axial and eccentric loading with and without expansive agent
چکیده انگلیسی
This paper presents the results of axial compression tests on recycled aggregate concrete (RAC) confined by glass fiber reinforced plastic (GFRP) tubes. The objective of this study is to evaluate the mechanical properties of GFRP-tube confined RAC under axial and eccentric compressive loading. The main parameters in the experiment are recycled coarse aggregate (RCA) replacement percentages (0%, 30%, 50%, 70% and 100%) and expansive agent contents (0%, 8% and 15%). Sixteen specimens were prepared, six specimens were tested under axial concentric compression load and ten specimens were tested under eccentric compression loading. Research findings indicate that both the RAC strength and deformation are obviously improved with the additions of expansive agent. It is also found that the peak stress of RAC confined by GFRP tubes decreases while the corresponding strain increases when the RCA replacement percentage is increased.
