Study on Impact Compressive Behavior and Constitutive Model of BFRC
Basalt fiber is a new type of high-performance fibers and it is widely studied and used in civil engineering. In this paper a super-thin basalt fiber was used and the samples of basalt fiber reinforced concrete (BFRC) were made, then the impact compressive experiments were conducted by SHPB and the factor of fiber content and loading velocity were study. The experimental result show that the super-short basalt fiber could increase the limit formation and change the failure modes of the sample, but it did not enhanced the strength of the concrete. The result also showed the limit load and deformation increase as the loading rate and it show that the BFRC have strain rate effect. Besides, based on the results of the experiments, the ZWT constitutive model being used, and the constitutive parameter were fitted.
