In order to improve the fracture performance of recycled aggregate concrete （RAC）， the effects of recycled coarse aggregate （RCA） and sisal fiber on the fracture performance of RAC were studied based on the three-point bending beam test by mixing sisal fiber into RAC. The results show that， compared with ordinary concrete， the initiation toughness， instability toughness and fracture energy of RAC without sisal fiber are reduced by 20.36%， 17.36% and 20.66%， respectively， when the replacement rate of RCA is 100%. When the length of sisal fiber is 10 mm， and its volume fraction is 0.2%， it has the best improvement effect on the initiation toughness of RAC， which is 37.81% higher than that of RAC without sisal fiber. In terms of instability toughness and fracture energy， the optimal volume fraction of sisal fiber is 0.3%. In summary， the incorporation of sisal fiber can effectively improve the fracture performance of RAC.
