What is the effect of fair faced concrete, and how to complete the basic construction method?

Fair-faced concrete is formed at one time, without any external decoration, and the natural color of concrete is directly used as the decoration color, which requires the surface of the beam and column plate to be smooth and smooth, the lines are regular and distinct, and the appearance color is consistent; The size of the axis is accurate; Large cross-section, variable cross-section structure, regular lines, sharp edges and corners; The beam-column joints are smooth and there are no obvious chariot marks; The concrete is solid inside and outside, eliminating the honeycomb surface and bubbles; The surface of the embedded parts and the embedded bolt casing is flat and the size is accurate; The position of the tie bolts is neatly arranged, and the formwork joints are regular. The concrete surface should not be damaged and contaminated.

The basic construction method can not be said to be complete, and we usually pour ordinary reinforced concrete, but in the concrete mix ratio, formwork assembly, steel binding and other aspects of the requirements are more stringent, the specific construction process is available on the Internet, if you can't find it, contact me, I will give it to you.

I checked a **, I don't know if it's displayed, you can look at the Shenzhen combat training base, as well as Vanke, as well as Shantou La Feiyi, etc., all of which are the effect of fair-faced concrete!

It is a kind of art paint, a bit like a tent in a military camp, with irregular shapes. You can refer to the specific construction method above, the first place in your "Chengmei Coating" is, I have several projects of Qingshui are in contact with them.

The effect is good, the template is good, the requirements are high, and common problems are not allowed.

Save the plastering process.

At present, it is very popular to imitate fair-faced concrete material, which is composed of three layers of bottom, middle and surface, and the whole process is similar to our batch of putty, and the effect after completion is also very good.

How to construct this kind of wall, the following is explained in detail.

If the wall is a cement wall, first do putty leveling, and after the putty is dry, polish and roll an anti-alkali primer.

After the alkali-resistant primer dries, scrape the art cement paint on it.

8. When dry, polish on top. At this point, you get a wall of clear water, isn't it easy?

Fair-faced concrete is the most advanced form of expression of concrete materials, it shows the most essential beauty, the final decorative effect of fair-faced concrete wall, 60% depends on the quality of concrete pouring, 40% depends on the later transparent protection spraying construction, therefore, it is a great challenge to the level of building construction.

In order to express the best effect of fair-faced concrete architectural style, the most important thing is still the pouring, maintenance and treatment of concrete walls.

1. Pouring stage.

Compared with the traditional concrete construction technology, the formwork requirements for fair-faced concrete construction are more stringent, and the design needs to be customized according to the building, and most of the formwork used is one-time, the cost is higher, and it is best to use imported formwork for important parts such as corners, beams and column joints;

The formwork must have sufficient rigidity, and no deformation is allowed under the action of concrete side pressure, so as to ensure the uniform geometric size of the structure and the consistency of the cross-section, and prevent the loss of slurry; There are also high requirements for the material of the template, the surface should be smooth and clean, with high strength, corrosion resistance, and a certain degree of water absorption; For the joints of the template and the bolts that fix the template, the joints are required to be tight, and the sealing strip should be added to prevent the slurry from running;

The tie rod of the fixed formwork also needs to be equipped with a metal cap or plastic buckle, so that it is convenient to remove the mold and reduce the damage to the concrete surface.

2. Maintenance stage.

The water absorption rate of the concrete surface is larger, if there is no protection, after wind and rain, the concrete will suffer from the damage of sunlight, ultraviolet rays, acid rain, oil and gas, oil pollution and other damage in the natural environment, and gradually lose its original appearance, and the concrete will be increasingly neutralized and destroyed over time, and its surface effect will become increasingly dirty, affecting the view. Therefore, transparent protective spraying on the surface of concrete can not only solve the problem of protecting concrete, make it more durable, but also can prevent pollution, keep clean, and will not become darker because of water absorption, so the fair-faced concrete building can still keep the color unchanged in the rain, and not like the urban overpass, it will be dirty when it rains, so it is also called dry spraying.

Fair-faced concrete is favored by everyone for its simple, natural and calm rhythm. So what is the construction method of fair-faced concrete? How to maintain fair-faced concrete floor? Let's take a look!

First of all, the ground must be treated first, and the ground must be clean and level. Secondly, the stirred slurry should be poured into the floor, and then flattened with a professional scraper plate, and cut out the dividing joints, and after the concrete ground is solidified, the ground should be smoothed with a grinder, first coarse grinding and then fine grinding. Finally, the concrete floor is cured and polished.

Fair-faced concrete floor curing:

The concrete should be removed when the strength reaches 3MPa. After the mold is removed, it should be cured in time to reduce the phenomenon of color difference and shrinkage cracks on the concrete surface. In addition, fair-faced concrete is generally cured by covering plastic film and sprinkling, and before removing the mold and during the curing process, it is necessary to frequently sprinkle water to keep it moist, and the curing time is not less than 7 days.

If you can't sprinkle water for maintenance in winter, you can use the curing method of brushing curing agent and plastic film, and the curing time is not less than 14 days.

Fair-faced concrete floor finished product protection:

In the follow-up construction, it is necessary to pay attention to the protection of fair-faced concrete, and do not collide and pollute the surface. Before the concrete is delivered, the exterior walls are protected with plastic film to prevent contamination. For the sunny corners, after removing the mold, it should be protected by nailing thin wooden strips or pasting hard plastic strips.

Education should also be strengthened to avoid man-made contamination or damage.

If the water is dry, the surface of the condensed soil will be repaired

When repairing visual defects, the following principles should be followed: different repair methods should be adopted for defects in different parts and different conditions, the color of the repair putty should be basically the same as that of fair-faced concrete, and the protection of finished fair-faced concrete products should be paid attention to when repairing, and water should be sprinkled and maintained in time after repair.

Article summary: Well, the relevant knowledge about what is the construction method of fair-faced concrete is introduced here, if you need to know more information about the infiltration of friends, please continue to pay attention to Qeeka Home, we will have better and more exciting content for you in the future.
