摘要：

To solve the technical difficulties of high water absorption of plant fibers and to improve the utilization of straw fibers as construction materials, four modifiers were used to modify Wheat straw fibers (WSFs). The water absorption, contact Angle, and tensile strength of WSFs before and after modification were characterized. FTIR, XRD, and SEM analyzed the chemical structure, crystallinity, and microstructure of WSFs. Finally, the water absorption, strength, and water resistance of wheat straw fiber cement-based composites (WSFCC) were tested. The results showed that the four modifiers could effectively reduce the water absorption of WSFs, improve the hydrophobicity and tensile strength of WSFs, and effectively improve the water absorption, strength, and water resistance of WSFCC. KH-550 has the best modification effect.
