In this paper, a method of controlling the apparent quality of fair-faced concrete is adopted. By adjusting the rheological parameters of fair-faced concrete slurry, the robustness interval of repeatedly stable preparation of fair-faced concrete with excellent apparent quality is obtained. It has a good economy and has a good guiding significance for practical engineering. The results show that the plastic viscosity coefficient of fair-faced concrete slurry is 5.67∼9.69 Pa·s, and the yield stress is between 112.25∼195.68 Pa. The fair-faced concrete with good apparent quality can be obtained.
