Embodiment Construction

[0027] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] A concrete surface treatment method before coating protective coating, the steps are as follows:

[0029] (1) Under ventilated conditions, the temperature is 23-26°C, the humidity is 45-55%, the concrete is poured and cured for at least 28 days; the relative humidity, dew point, and ambient temperature can be measured with a hand-operated dry-humidity thermometer. construction surface to obtain accurate data.

[0030] (2) Cut off the exposed steel head, cut a hole not less than twice the width of the steel bar inside the con...

Abstract

A method for achieving concrete surface treatment before coating of a protection coating comprises the following steps that (1) concrete is poured and maintained for at least 28 days; (2) exposed steel bar ends are cut off, holes not smaller than two times of width of the diameter of steel bars are chiseled into the concrete, and the holes are filled with repair materials; (3) cracks are repaired, hollow portions are removed and exposed, and the hollow portions are filled with filling materials matched with the concrete; (4) different renovation materials are selected according to holes of different renovation thicknesses for renovation; (5) surface evenness treatment is carried out; and (6) surface cleaning is carried out. The method is simple in operation, a treated concrete surface layer is large in strength, resistant to corrosion, clean and level, and coating of the protection coating is easy.

Description

technical field [0001] The invention relates to a concrete surface treatment method before coating a protective coating, and belongs to the technical field of concrete surfaces. Background technique [0002] The protective performance of the concrete protective coating is directly related to whether the concrete surface treatment is appropriate. Reasonable and standardized concrete surface treatment can make the protective coating play the best performance and protect the concrete against erosion. Inappropriate and irregular Concrete surface preparation can cause premature failure of the protective coating, resulting in severe erosion of the concrete. It is precisely because of the above reasons that it is necessary to choose the correct concrete surface treatment and inspection methods in order to make the protective coating effectively protect the concrete. However, there is no effective concrete surface treatment at present, so the concrete coated with protective coating...
