This study aims to convert waste rock into sustainable building materials by using it as coarse and fine aggregates prepare basalt fiber steel fiber-reinforced concrete (BFRC SFRC). The optimal dosages reinforcement mechanism of fibers were determined through mechanical performance tests, P-wave velocity slump SEM analysis. Experimental research shows that incorporating an appropriate amount can improve the concrete, all BFRC SFRC specimens meet strength requirements. achieves best strengths with 40 kg/m3 2 fiber. Compared control specimens, greatly improves tensile 22.2% flexural 27.4%, increases them 20.2% 17.4%, respectively. Although exhibit higher strengths, production cost CO2 emissions are significantly higher, 2.46 times 1.21 than BFRC. analysis revealed incorporation dosage resulted in a denser microstructure within matrix. Basalt high elastic modulus provide significant bridging effects crack resistance. uniform distribution forms dense network structure, limiting generation propagation microcracks, thereby improving properties. Overall, addition may be more favorable choice. Besides, this provides theoretical basis for resource utilization contributes promoting application engineering.
