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… More >
