In this paper, the impact of synthetic fiber content and vibration time on the strength of concrete is studied, with the conclusion that the concrete flexural strength decreases with the increase of fiber content, but that properly lengthening the vibration time can eliminate the negative impact of synthetic fiber on concrete.
