In this study, acrylic acid (AA) and grapheme oxide (GO) were grafted onto the surface of PP fabric in order to improve mechanical property and freeze-thaw durability of PP fabric reinforced concrete composites. Results showed that the successful graft of AA and GO increased the surface roughness of PP fabric as well as improved the hydrophilicity of PP fabric. Compressive property of modified PP fabric reinforced concrete composites showed slight increase. Flexural strength of PP-g-AA-GO fabric reinforced concrete composites increased by 25.6% compared with that of pristine PP fabric reinforced concrete composites. The addition of various PP fabrics in concrete significantly improved its freeze-thaw durability. PP-g-AA-GO fabric reinforced concrete composites achieved the highest relative dynamic modulus of elastic and residual flexural strength, as well as mass remaining percentage.
