Abstract: This paper adopts a contrastive experimental method to design and prepare reed fiber concrete. It discusses the influence of reed fiber content (2%), fiber length (1.5 cm for short reed fiber and 3 cm for long reed fiber), and moisture content (0% for dry fiber and 85% for wet fiber) on the mechanical properties of concrete, and compares it with the reference concrete without reed fiber. The experiment obtained the flexural and compressive strength of reed concrete, and analyzed the apparent mechanism of concrete specimens after failure. The experimental results show that the addition of reed fiber enhances the mechanical properties of concrete, the compressive strength of concrete increases by 1.13 MPa compared with the reference concrete, and the flexural strength increases by 2.32 MPa. The flexural performance of reed fiber reinforced concrete with 3 cm dry fiber and 0% moisture content is the highest, reaching 3.5 MPa; the compressive performance of reed fiber reinforced concrete with 85% moisture content and short reed fiber is the highest, reaching 2.69 MPa. This paper shows that adding 2% of reed fiber to concrete is feasible, and adding 1.5 cm, 85% moisture content wet reed fiber can better promote the mechanical properties of reed fiber concrete.
