Abstract

The invention belongs to the technical field of concrete preparation and construction, and discloses an imitated bare concrete protective agent and a construction method. The imitated bare concrete protective agent is prepared from polymer repair mortar, a surface layer repair material, an alkali-resistant seal primer and two bare concrete protective reagents. The imitated bare concrete protective agent is prepared through an improved formula, hollowing and falling can be effectively avoided, the decoration effect is good, secondary decoration of materials such as putty is not needed during outdoor decoration, the cost is reduced, and the economical efficiency is good. The construction method comprises the following steps that S1, a concrete base surface is cleaned, and defects are repaired; S2, the surface of a wall is coated with an alkali-resistant seal primer; S3, scraping a surface layer repairing material on the surface of the wall; S4, after the surface is dried, conducting polishing; S5, conducting pattern drawing by a pattern drawing roller; S6, brushing a bare concrete protective agent embellish component; S7, after the surface is dried, conducting polishing; and S8, coating the surface with the fair-faced concrete protective agent facing component. The construction method is fine in implementation, high in pertinence, good in decoration finished product effect and harmonious in finished product appearance color.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an imitation fair-faced concrete protective agent and a construction method thereof. Background technique [0002] With the development of the technical level of my country's construction industry, the rise of green buildings, low-carbon buildings, ecological buildings, etc., the self-igniting texture of fair-faced concrete, without decoration and decoration, has attracted widespread attention. It is used in public construction projects such as viaduct piers. [0003] Concrete is poured after mixing cement, aggregate and some additives. If the concrete is exposed to harsh environments such as air pollution, ultraviolet rays, and acid rain for a long time, the surface of the concrete will be carbonized and corroded by chlorides, and then cracks will occur, affecting Exterior quality and durability. Usually, people improve the durability of concrete by adopting post-repair and co...
