Abstract
This paper presents an experimental study to explore the compressive properties of fiber recycled aggregate concrete. A total of 75 specimens with the replacement rate of recycled coarse aggregate and fiber type were conducted under a uniaxial compressive test. The failure modes, stress-strain whole curves, peak stress, peak
strain, and energy dissipation capacity were systematically observed and revealed. Test results indicate that steel
fiber has the best modification effect on energy dissipation capacity and the toughness index of recycled concrete,
corresponding to the enhancement of 81.75% and 22.90% on average. The addition of polyvinyl alcohol fiber can
effectively improve the compressive strength and energy dissipation capacity of recycled aggregate concrete by
28.49% and 29.43% on average, respectively. The compressive strength and energy dissipation capacity of recycled
aggregate concrete is increased by an average of 16.5% and 24.4% by incorporating carbon fiber. The energy dissipation capacity of recycled aggregate concrete is increased by an average of 13.5% with the incorporation of
polypropylene fiber. However, the addition of carbon fiber results in a slight reduction of toughness by
16.97%, and the effect of polyvinyl alcohol fiber on the energy dissipation capacity is limited. Besides, with the
increase in replacement rate, the compressive strength and the energy dissipation capacity of recycled coarse
aggregate concrete with fiber decreased, and toughness first decreased and then increased. Finally, based on
the analysis of test data, a segment-based stress-strain model of fiber recycled aggregate concrete was proposed,
which shows good agreement with the test results.
