Production method of sand blast fair-faced concrete
The invention relates to the field of buildings and particularly relates to a production method of sand blast fair-faced concrete. The production method comprises the following steps of a, carrying out sand blast treatment on a molding surface of a mould, wherein the particle size of the blasted fine sand is smaller than 1.5mm, and the color of the sand blasted on the molding surface of the mould is uniform; b, placing a steel reinforcement cage into the mould; c, pouring the stirred concrete into the mould, and screeding the upper surface of the concrete in the mould; and d, dismounting the mould after the strength of the concrete meets the requirement, and spraying a protective agent on the fair-faced surface of the molded concrete to obtain the sand blast fair-faced concrete. The fine sand is sprayed on the molding surface of the mould, and flaws on the molding surface of the mould are removed, so that the molding surface of the mould is more smooth and is uniform in color, pot holes in the surface of the concrete are avoided, the concrete is molded at one time without mending, the concrete is kept uniform in veneering color and free of air bubbles and has a matting effect, the construction cost is further reduced, and the work efficiency is increased.
