Production method for coated bare concrete

Abstract

The invention relates to the field of buildings, in particular to a production method for coated bare concrete. The production method comprises the following steps that a, a layer of thin film is laid on the molding surface of a mold, so that the thin film is flatly attached to the molding surface of the mold; b, the surface of the thin film is smeared with mold-releasing oil; c, a steel reinforcement cage is put into the mold; d, stirred concrete is poured into the mold, and the upper surface of the concrete inside the mold is flattened; and e, after the intensity of the concrete meets the requirements, the mold is detached, the bare face of the molded concrete is sprayed with protective agents, and the product is obtained. The surface of the thin film is flat and smooth, rubbish or rust is not likely to adhere to the surface of the thin film, the decorative effect of the bare face of the concrete can be ensured only by laying one layer of thin film on the mold, hollows in the surface of the concrete are avoided, the concrete is molded at a time and does not need to be repaired, and the veneer colors of the concrete are uniform.

Description

technical field [0001] The invention relates to the construction field, in particular to a production method of coated fair-faced concrete. Background technique [0002] Fair-faced concrete (As-cast Finish Concrete / Bare Concrete) is also known as decorative concrete; it gets its name because of its very decorative effect. It belongs to one-time casting molding, and its surface has the texture of natural stone, and it can be smooth and smooth without any decoration. Therefore, the surface quality of the mold for producing fair-faced concrete directly affects the decorative surface of fair-faced concrete. [0003] However, after repeated use of the current mold for producing fair-faced concrete, many rubbish and rust spots that are not easy to clean are easily stuck on the surface. There are potholes, which need to be repaired and plastered, which wastes a lot of financial and material resources and increases the project cost. Moreover, chromatic aberration is prone to occur...

[0003] However, after repeated use of the current mold for producing fair-faced concrete, many rubbish and rust spots that are not easy to clean are easily stuck on the surface. There are potholes, which need to be repaired and plastered, which wastes a lot of financial and material resources and increases the project cost

Moreover, color difference is prone to appear in the repaired place, which seriously affects the decorative effect of fair-faced concrete and reduces the quality of fair-faced concrete.
