摘      要：In this paper,a notched three-point bending test is used to study the fracture performance of the short basalt fiber bundle reinforced concrete(SBFBRC).To compare and analyze the enhancement effect of different diameters and different content of basalt fiber bundles on the fracture performance of concrete,some groups are set up,and the P-CMOD curves of each group of specimens are measured,and the fracture toughness and fracture energy of each control group are *** fracture toughness and fracture energy are two important fracture performance parameters to study the effect and law of the new basalt fiber bundles on the fracture performance of *** research results show that the diameter and content of the new basalt fiber bundles have a certain effect on the fracture performance of *** the increase of the content of basalt fiber bundles,the peak load,crack initiation toughness,instability toughness and fracture energy of SBFBRC are greatly improved compared with the benchmark *** the fiber bundle diameter is 0.2 mm,the peak load increases by 69.5%compared with the reference *** instability toughness reaches its maximum value at 0.2 mm diameter,which is 59.7%higher than the benchmark.
