Abstract: The fiber mixing effect of polyvinyl alcohol fiber and polyester fiber on the mechanical properties of sulphoaluminate cement-based ECC (SAC-ECC) was studied based on the benchmark mix ratio, and the fiber reinforcement coefficient and the mixing effect coefficient were also used to evaluate the mixing effect of these two fibers. The results show that the fluidity and apparent porosity of PVA-ECC are higher than those of PET-ECC with the same volume content of fiber addition, but the apparent porosity and fluidity of ECC with mixed additive of PVA and PET fibers are between the values of the ECC with additive of PVA or PET alone. With the increase of addition content of PVA and PET fiber, the flexural and compressive strength of SAC-ECC decreased first and then increased, and the strength of specimen with PET fiber was higher than that with PVA under the same addition content. The positive mixing effect of PVA fiber and PET fiber can further improve the tensile and compressive strength, and with the PVA∶PET mixing ratio of 1∶2, the strength of SAC-ECC is highest. The mixed fibers had a good effect on improving the bonding strength of ECC and basalt fiber reinforced polymer (BFRP) bars, while the single doped 0.3%PET fibers had a better effect on improving the bonding performance of new and old cement-based materials.
