To improve the fracture performance of recycled aggregate concrete (RAC), the effects of steel fiber, sisal fiber, and steel-sisal hybrid fiber on the fracture performance of RAC specimens were studied through three-point bending fracture tests. At the same time, digital image correlation (DIC) technology was used to measure the entire process of crack propagation in RAC specimens. The results show that the fracture performance of RAC specimens without fiber addition is poor, while the fracture performance of RAC specimens with fiber addition is significantly improved. When steel fiber is single doped, the cracking toughness is not related to fiber content. When sisal fiber is single doped, the optimal volume content is 0.15%, the initiation load of RAC specimen is 67% higher than that of RAC specimen without fiber addition. Both single doped and hybrid fiber can improve instability toughness and fracture energy, but hybrid fiber has a better effect. When steel fiber with a volume fraction of 1.0% and sisal fiber with a volume fraction of 0.30% are mixed, initiation toughness, unstable toughness and fracture energy of RAC specimens increase by 83.92%, 575.86%, and 1 244.05% compared with RAC specimen without fiber addition, respectively.
