Embodiment Construction

[0016] Below in conjunction with specific embodiment the present invention is described in further detail:

[0017] The fair-faced concrete defect repair process specifically includes the following steps:

[0018] A. Surface pretreatment: First, clean the surface of the wall and water it to make it ready for the next step.

[0019] B. Surface filling: a. Treatment of air bubble holes: Use repairing materials to make up air bubble holes one by one. After the repair is completed, cure and dry, and then polish it with fine sandpaper. After polishing, rinse with clean water and dry; b. Formwork seam treatment: First use an angle grinder to grind the unevenness of the seam, and then use a grinder to polish it. If there are serious flaws, such as local vibration leakage, the area is greater than 0.5cm 2 , the honeycomb and pitted surface with a depth greater than 10mm, or the strip joints with a length greater than 50mm due to the inconsistency of the secondary pouring slurry, etc....

Abstract

The invention discloses a repairing technology for fair-faced concrete defects. The repairing technology comprises the steps of surface pretreatment; surface filling; surface color treatment. The surface pretreatment step comprises the operation of cleaning a wall surface, wetting the wall surface through water and preparing for the next step. The surface filling step comprises the operation of a, bubble type hole treatment, wherein bubble type holes are remedied one by one through repairing material, then cured and dried after remedying is completed, polished through fine abrasive paper, washed cleanly through clean water after polishing is completed and finally air-dried; b, formwork joint treatment, wherein uneven parts of joints are ground by an angle grinder and then polished by a polishing machine, and the parts with serious defects need to be leveled through the repairing material. The surface color treatment step comprises the operation of carrying out color treatment on repaired parts of the surface of the wall body through concrete color matching agents; carrying out paint surface painting, wherein the repaired surface of the wall body is wholly painted with concrete protection paint. According to the technology, the treated surface of fair-faced concrete can be the same as the original surface, the appearance effect is good, and the concrete protection paint is additionally used so that protection to the surface of the concrete can be enhanced.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a process for repairing surface defects of fair-faced concrete. Background technique [0002] Regardless of the level of on-site management in the construction of fair-faced concrete, it is impossible to carry out the construction of concrete under very ideal conditions. Often due to various reasons, or the special structure type, or the bad weather conditions, or the construction method, Irregular construction techniques, such as: improper vibrating method, or not tight formwork connection, insufficient protection of finished products, etc., resulting in defects such as air bubbles on the concrete surface, obvious joints on the concrete surface, and inconsistent colors. No matter what kind of surface defect it is, it will have an adverse effect on the appearance quality of concrete. Therefore, it is necessary to repair the defects necessary to improve the appea...
