<p>The crack propagation process of basalt fiber-reinforced concrete was explored using the mesoscale peridynamics (PD) method. The compressive and splitting tensile tests of basalt fiber-reinforced concrete were carried out. The constitutive model of concrete three-phase material was developed based on the micropolar peridynamic model, and the fiber-mortar mixture model was established by homogenization technology. The simulation results were compared with the experimental data. In addition, the effects of aggregate ratio and fiber content on crack development were studied. The experimental results showed that basalt fibers effectively improve the compressive and split tensile strengths of concrete. The microscopic analysis showed that the uniaxial compression and splitting tensile crack patterns of basalt fiber-reinforced concrete were consistent with the experimental results. Under axial compression, the cracks are funnel-shaped. Under split tension loading, the crack form is vertical through crack. Increasing the aggregate volume fraction and fiber content delayed the time of crack occurrence to varying degrees.</p>
