Technical Field

The invention relates to the field of concrete defect repair, in particular to a concrete defect repair reinforcement and color difference processing construction method.

Background

At present, in concrete defect repair treatment, including but not limited to concrete crack treatment, concrete surface damage repair, honeycomb pitted surface treatment and other repair methods, the color of the concrete surface is different after repair due to the diversification of repair materials, the color difference is serious, the attractiveness is influenced, even the acceptance is influenced, the whole effect of a building is influenced, and due to the single repair construction mode, the secondary damage of a concrete matrix to be repaired is easily caused, and the repair quality and efficiency of concrete are reduced.

In the chinese patent concrete crack repairing structure and repairing method with patent number CN201810306140, the author only provides a method for repairing cracks, but does not solve the problem of repairing marks after repairing, which may cause serious repairing marks on the surface of concrete and affect the overall beauty of concrete.

Disclosure of Invention

The invention aims to solve the problems and provide a concrete defect repairing, reinforcing and color difference processing construction method.

The invention realizes the purpose through the following technical scheme:

A concrete defect repairing, reinforcing and color difference processing construction method comprises the following steps:

Step 1: the method has the advantages that dust and stains on the damaged part on the surface of the concrete are cleaned, so that the influence of the dust and the stains on crack repair is effectively prevented, and the repair quality of the concrete is ensured;

Step 2: injecting a concrete repairing agent into the defect part, and polishing the surface of the concrete repairing agent after the concrete repairing agent is cured, wherein the concrete repairing agent is a 10-minute concrete repairing agent, has strong seepage force and short action time, and greatly improves the repairing efficiency;

and step 3: after the surface is polished to be flat, preparing a base coating material according to the color of the peripheral concrete, brushing the prepared base coating material on a repaired part by using a roller, and completely covering the repaired part so as to facilitate the subsequent paint color mixing treatment;

And 4, step 4: and then, the design and color finish paint is prepared according to the color of the peripheral concrete, more than three colors are prepared for the design and color finish paint, and the prepared design and color finish paint is subjected to finish paint patting and coating by using special felts or seaweed blocks, so that the finish paint has natural and irregular images, and is naturally linked with the color of the peripheral concrete to form a whole, the whole color of the concrete after being repaired is consistent, the whole appearance is attractive, and the pass rate of engineering acceptance is improved.

Further, the step 1 is mainly operated by an external air compressor when cleaning dust on the damaged concrete.

furthermore, the concrete repairing agent in the step 2 has strong self-permeability, can penetrate a crack with the depth of 50 cm of 0.2 mm without pressurization, does not contain a solvent, can be completely cured to form a hard material which is completely bonded with the concrete, has the strength of 30 MPa and micro toughness, and can be cured within 10-20 minutes.

Furthermore, the design and color finish in the step 4 is the same as the design and color finish in the prior art, so that the corresponding color can be conveniently blended according to the actual repairing requirement, and the color difference of the repaired concrete can be avoided.

the invention has the beneficial effects that:

1. The invention not only can repair concrete cracks and concrete surface damages more quickly and simply, but also can restore the original color and the design color of the concrete, so that the overall color and the design color of the concrete are consistent and the overall appearance is attractive, the problem of poor color of the concrete can be effectively solved, and the pass rate of engineering acceptance is improved;

2. according to the invention, by adopting the corresponding repairing treatment method according to the type of the crack, the rapid repairing of the concrete can be realized on the premise of not damaging the original concrete matrix, the repairing quality and efficiency of the concrete are ensured, and the secondary damage of the concrete matrix is avoided.
