What are the concrete repair schemes, concrete repair measures?

First of all, the loose stones of the concrete defect part are removed, rinsed with clean water, and then compared with the original concrete strength for the defects on the concrete surface, in principle, the number and part of the repair are as small as possible.

Clause.

1. For small bubble defects, clean them with water and then compact and apply them evenly with 2:1 cement mortar. When encountering defects similar to small bubbles on the surface, this is easier to repair, first rinse the dust and excess impurities on the surface of the concrete with water, so as not to affect the repair effect, and then the cement mortar is used in 2:

Stir the ratio of 1 well, then apply repeatedly on the surface of the small bubbles, and then compact after the small bubbles disappear.

Clause. 2. Expose defects in the steel bar, clean it with water, and then cover the surface of the steel bar with 1:2 cement mortar. If you encounter defects in the exposed steel bar, don't be too anxious, you can first rinse the surface with water to keep it clean and tidy, and then use 1:

2. Mix the cement mortar evenly, and then cover the cement mortar on the exposed steel bar surface and apply it flat.

Clause. Third, the depression hole defects, the depression around the loose, with a high strength of semi-dry fine stone concrete filling. The depression hole is a more serious defect, it is necessary to evacuate the defect first, and then use pressure water to rinse vigorously to ensure the wetness of the surface, and then fill it with fine stone concrete with high strength, and repair it regularly after repair.

Repair of concrete:

1.Fissure. Patching Method:

First of all, the concrete surface near the crack is pretreated, the floating slurry, floating ash, oil stains and other objects on the surface of the base are removed, the loose parts such as pimples and delamination on the surface and the loose stones on the honeycomb and hemp surface are removed, and washed with water, and then the base concrete is fully soaked with water.

Then use a nylon brush to evenly apply the repair mortar to the repaired surface by the circular brushing method, control the thickness of the coating, and cure it for no less than 2 days after 2 4 hours after brushing, and cover it with moisture.

2.Bubble. Patching Method:

First, clean the base concrete near the bubble with a brush, fully soak the pores with water, and then repair it with cement mortar, and after drying, polish the repair surface with fine sandpaper, so that the repair place and the nearby prefabricated components are flattened as a whole, and the repair color difference is reduced.

3.Missing edges and corners.

Repair method: clean the parts that need to be repaired, chisel if necessary, and then soak the base layer with water. Then the concrete surface is painted with cement mortar, and the formwork is repaired, and the repair material is fine stone concrete or prefabricated component concrete of the same grade.

After repair, moisturizing and curing should not be less than 7 days. After drying, polish the repair surface with fine sandpaper to make the repair and the prefabricated component as a whole, and reduce the color difference between the repair and the prefabricated component.

Patches for concrete.

1.First of all, the quality inspector will inspect the components after the mold is released on site, and identify the components that need to be repaired, and judge the type of defects.

2.The base concrete residue is cleaned and repaired with a special repair material (the same strength grade as concrete).

3.After the repair material is solidified, it is regularly sprinkled with water for maintenance. If it is found that there is cracking, falling off, etc., it will be smashed again and repaired.

4.The quality inspectors supervise the whole process and evaluate the repair quality according to the evaluation standards.

The damaged ground can be repaired with a professional concrete repair agent, and then hardened with a hardening agent for the concrete sealant.

Deligu concrete sealing and curing agent construction process:

1. Polishing or repairing the sand damaged layer, for the new ground, the ground must be cleaned first and then coarsely grinded, for the old ground, if there is damage and sanding, then use Deli concrete repair agent to repair and then polish.

2. After coarse grinding on the ground, the sealing penetrant material is evenly poured on the ground, and soaked for 4 hours and then cleaned with water.

3。Coarse grinding of the ground, after the material is cleaned, the ground is coarsely ground with a resin grinding disc, which is to allow the material to penetrate the inside of the ground concrete for a chemical reaction.

4. Pressure permeability ground curing agent B, concrete sealing curing agent B agent soaked for 4 hours, so that the material and concrete fully react to form a dense and hard entity.

5. The concrete resin sheet is finely ground to penetrate the concrete dense excavation sensitive sealing curing agent material more deeply, and the response is more sufficient, forming a smooth, wear-resistant, durable, compression-resistant, sand-free, dust-free floor.

6. Polishing, the hardness of the ground has been significantly improved at this time, in order to make the surface more bright and wear-resistant, the ground is polished to form a durable and compression-resistant wear-resistant hardened floor.

Whether it is in our home improvement construction or on the outdoor construction site, we can not avoid the use of concrete, which plays a very important role in Yuyun construction. So how do we repair the broken concrete? Today, I will tell you some tips for concrete damage and repair.

I hope it can help everyone in Heqiao to solve the problem of asking questions, and interested friends can learn about it together.

1. Tips for repairing concrete after it is damaged.

1. The damaged concrete can be repaired quickly by smearing and covering the method. First of all, we can use the manual spraying method, and then adjust the repair material to apply to the concrete, and then close the surface of the concrete, this method can repair the damaged concrete well.

2. Add a layer of cement mortar on top of the concrete, this method can also repair the damaged concrete.

3. If the number of damaged concrete is not large and the concrete area is not concentrated, we can also use press-coated epoxy cement glue for repair, or use epoxy slurry glue to paste the glass cloth grid, and divide it on top of the damaged cement concrete.

4. We can also use the method of surface stitching to repair the damaged concrete, we can drill holes or groove on both sides of the concrete cracks, and then put the U-shaped steel bar in the groove, and then pour the epoxy resin into the groove, and wait for fixation, we can quickly repair the damaged concrete.

The above is a summary of the relevant information and methods on how to repair concrete damage, I hope it can help you, if you have any other questions, you can leave a message below the platform, and you will solve the problem in time. Finally, if you have any questions about home furnishing and home decoration, you can pay more attention to Qeeka Home, and Qeeka Home will provide you with more professional answers.

I believe everyone knows that although fair-faced concrete has only appeared in recent years, it has been recognized by countless owners through its excellent functions. So, what is the repair plan for seepage fair-faced concrete? What are the advantages of concrete?

Let's find out together!

1. What is the fair-faced concrete repair plan?

First of all, be sure to clean up the clutter on the wall, and at the same time make sure that the wall is dry. The material is then rolled out and integrated into the concrete. Within half an hour, the dried area should be repaired, and the accumulated area should be evenly applied.

In the end, just apply it a few more times.

2. What are the advantages of concrete?

1. Plasticity.

Contemporary concrete production generally has a very superior effect. In general, concrete can be made into a variety of buildings through formwork and design, which shows that it is very malleable.

2. Economical.

Compared with other decoration materials, concrete will be more cost-effective. Because concrete can be made of local materials, and there is no need for maintenance costs when the structure is formed, it has become the first choice of countless decorators.

3. Fire-resistant. Typically, concrete can resist a fire for one to two hours. Therefore, compared with steel, concrete is safer, and it will not soften immediately when it encounters a fire like a steel structure building, thus inducing dangerous accidents.

4. Durability.

In fact, concrete itself is a very durable material, for example, the concrete in ancient Roman buildings has been used for thousands of years, but it is still strong enough.

Summary: The above has introduced to you what the fair-faced concrete repair scheme is and what the advantages of concrete are, and I hope to give you some small help.
