摘要：
In order to study the effect of adding steel-basalt hybrid fiber on concrete cracks, the axial tensile test of steel-basalt hybrid fiber reinforced concrete specimens was designed.The test emphatically analyzed the effect of different steel-basalt hybrid fiber contents on the crack morphology, initial crack load, crack spacing, crack width of concrete and fiber confounding effects.The test results showed that the incorporation of steel-basalt hybrid fiber could significantly change the crack morphology of the concrete, manifested as the increase in the initial crack load and the decrease in the crack width.Excessive hybrid fiber content increased the risk of fiber agglomeration and negative hybrid effect, which resulting in a rebound in the control effect of steel-basalt hybrid fiber reinforced concrete on the crack width. © 2023 Huazhong University of Science and Technology.
