Abstract

Improving the tensile, flexural, and shear strength of concrete is always the focus of research because the poor tensile property of concrete is relatively poor. Base on the mechanical performance test of short-cut basalt fiber concrete, the influence of fiber content and fiber length on split tensile strength, flexural strength, and shear strength of basalt fiber concrete were discussed in this paper. With the increase of short-cut basalt fiber content, the split tensile strength and flexural strength were respectively increased by 13.3% and 16.9%, but the shear strength of basalt fiber concrete specimens was lower than reference concrete specimens. With the same fiber content, the monofilament length of short-cut basalt fiber was increased, the shear strength recovered to the level of reference concrete. When the fiber content was 0.1% and the length of the fiber concrete specimens was 12mm, the split tensile strength of the fiber concrete specimen was 13.3% higher than that of the reference concrete specimens. According to the test results, increasing the content and length of fibers could effectively improve the tensile properties of concrete materials.
