What is the constituent material of fair faced concrete

Fair-faced concrete is only a one-time pouring molding, without any external decoration, directly using the natural surface effect of cast-in-place concrete as the finish, and coating one or two layers of transparent protective agent on the surface, which is very natural and solemn. Fair-faced concrete 60 depends on the quality of concrete pouring, 40 depends on the transparent protection spraying construction in the early stage, the concrete ratio is the same as the ordinary, but the raw materials, formwork requirements are strict, the origin must be opposed, and the cement used can be used in the same batch of the same manufacturer; The color and particle gradation of sand and stone are average.

The formwork must have sufficient stiffness, and there is no deformation under the action of concrete side pressure, so as to ensure the average geometric size of the structure and the consistency of the cross-section.

Summary. The mix ratio of fair-faced concrete is: cement, water-cement ratio pebble particle size 10 30, medium coarse sand.

Materials per cubic concrete: 394 kg of cement, 185 kg of water, 571 kg of medium coarse sand, 1250 kg of pebble grains.

What is the formula of fair-faced concrete.

The raw materials of fair-faced concrete are cement, sand (fine bone), sand and gravel (coarse bone) and water. Those without sand and gravel are called "mortar".

It is an expression of architectural modernism, which is very decorative. The basic idea is that after the concrete is poured, there is no longer any painting, tiling, stone and other materials, which is a no-makeup technique for concrete. However, due to the fear of being soaked or deteriorated by rain, a layer of waterproof protective film may be sprayed.

Since fair-faced concrete will no longer have other decorative materials, it is necessary to pay great attention to the provisions of the reinforced concrete protective layer in the construction specifications for the resistance of wind and rain, so it is necessary to be very careful in the construction stage, and the contractor and the builder often stay away from it.

However, the unique strength, cleanliness, and material of fair-faced concrete structure are particularly appreciated by designers with strong personalities.

In addition, because fair-faced concrete lacks the decoration project after dismantling the formwork, it roughly determines its quality in the stage of forming the formwork. In contrast to the traditional preference for plain wood in wooden architecture, the high construction skills of the modelers and the precision of the finished hidden stove are known as "family heirlooms" in Japan.

The texture of fair-faced concrete itself with different elements can show different rhythms, which really reflects the construction process of fair-faced concrete, and is also the basic language of fair-faced concrete building beauty cover leakage. Coupled with the advantages of low-carbon and environmental protection of fair-faced concrete, it has attracted wide attention in the construction field. The reason why fair-faced concrete has not sounded in the country for a period of time is not unrelated to its construction technology, there are too few companies with mature technology in China, so that we do not know about fair-faced concrete, and the decorative effect of fair-faced concrete can be realized through unique technological techniques to create a different decorative experience.

Fair-faced concrete is a commonly used building material, in which water is one of its main components. It is made from a mixture of water, cement, sand and gravel, and no other admixtures or chemical additives are added during construction.

The process of making fair-faced concrete involves mixing cement, sand, and gravel in a certain proportion and adding an appropriate amount of water to stir until a homogeneous slurry is formed. This mixing process can be carried out manually or using equipment such as concrete mixers or concrete tankers.

Fair-faced concrete is often used for pouring foundations, grounds, columns, beams and other parts of various building structures at the construction site. It has the characteristics of high strength, good durability and low cost, so it is widely used in building engineering.

The production and construction of fair-faced concrete requires strict control of the proportion of cement, sand, and gravel and the mixing time to ensure the quality and performance of concrete. In addition, it is also necessary to pay attention to keeping the construction site clean during the construction process, and remove the floating soil and air holes on the concrete surface in time to ensure the quality and appearance of the concrete.

Fair-faced concrete protector material is a material used to protect the surface of concrete, which can make the decorative effect of fair-faced concrete in different finishes. It is usually composed of resins, pigments, solvents, and fillers, and has a certain viscosity and viscosity. Fair-faced concrete coatings can provide protection and decoration on the surface of concrete, which can prevent moisture and chemicals from penetrating the inside of concrete, and prolong the service life of concrete.

In addition, it can also play a role in preventing pollution, dust, and increasing anti-slip functions. Fair-faced concrete coatings are usually suitable for indoor and outdoor concrete structures, such as floors, walls, ceilings, etc.

Nowadays, many places are using water concrete, especially some wall decorations, fair-faced concrete has high practicability, and gives people a natural and simple feeling, but there are many people who don't know what fair-faced concrete is.

Fair-faced concrete is that after the concrete is constructed on the wall, there will be no other decoration on the surface of the wall, including tiles, stones and coatings, etc., and the wall will only have a layer of concrete. Clear water concrete is a more popular decorative technique now, giving people a sense of beauty without makeup. However, this kind of concrete is easily corroded or weathered by rainwater, so the surface will be sprayed with a layer of waterproof membrane.

Fair-faced concrete is a relatively green and environmentally friendly concrete, which does not need other decoration, removes some chemical products of paint and decorative materials, is very simple to seep hail, and can be formed at one time, and does not need to be plastered or repaired. It has an unpretentious, natural and calm appearance, and the innate heaviness and elegance are incomparable to some modern building materials. The softness, rigidity, warmth, and indifference of the material itself not only have an impact on people's senses and spirit, but also can express the emotion of architecture.

The biggest difficulty in fair-faced concrete technology is that the comprehensive cost of fair-faced concrete, such as cost, process, and so on, is not something that our market can grasp freely now, and even in Japan, it is a challenge to use fair-faced concrete on a large scale. In addition, I am afraid that there will be a little problem in aesthetic habits, if you feel that the wall is uneven after removing the template, you will wipe the cement to find it, but it will destroy the texture.

Fair-faced concrete is a veritable green concrete, fair-faced concrete natural and steady, unpretentious appearance taste, and itself and elegant and heavy is now some decoration materials have no way to compare. The warmth, softness and rigidity of fair-faced concrete not only have a huge impact on our sensory experience, but also express the emotion of the building. Therefore, most architects believe that fair-faced concrete looks simple, but it is more in line with modern aesthetic needs than the splendid decoration, which can be said to be a kind of gorgeous simplicity.

Fair-faced concrete is also known as decorative concrete, and fair-faced concrete is a high-grade type of concrete. It is named decorative concrete because it is very decorative. Fair-faced concrete is a one-time molding, not modified on the appearance, is the ready-made surface of cast-in-place concrete without any whitewashed wall, fair-faced concrete is much better than ordinary concrete, better than ordinary surface color, three-dimensional, smooth surface, will not pollute the environment and so on.

It's just that there are a few more layers of protective agent than ordinary concrete, and it will appear more natural and harmonious.

Fair-faced concrete is a typical green concrete, which does not need to be decorated when composing, eliminating chemical products such as coatings and finishes, which is conducive to environmental protection. In addition, fair-faced concrete is formed at one time, which does not require plastering and repair, and saves a lot of construction waste. In addition to environmental protection, fair-faced concrete also avoids quality hazards such as cracking, hollowing and falling off, and reduces the quality problems of the project.

What are the characteristics of fair-faced concrete?

The finish of fair-faced concrete needs to be protected by fair-faced concrete protective agent after decoration, so that the fair-faced concrete finish is not eroded by foreign substances

1) One-way breathing and air permeability to prevent external rain, moisture, carbon dioxide and other harmful gases from penetrating into the system, and at the same time, the moisture in the system can be emitted normally.

2) Prevent the occurrence of concrete cracks in the early stage, and waterproofing can prevent the generation of concrete microcracks.

3) Improve the compressive and flexural strength of concrete and stone, and the waterproof effect continues.

4) Good freeze-thaw stability, strong permeability, can not change the texture and texture of the substrate after painting, anti-mold growth, anti-staining, salt, acid, alkali and other corrosion.

Fair-faced concrete has many applications in life and is loved by many people. At the same time, what are the characteristics of fair-faced concrete, of course, after not seeing it, you will know why it can have such a high sales volume and be loved by so many people, and at the same time, it is necessary to do a good job of maintenance and care for fair-faced concrete. The application field of fair-faced concrete is also expanding, such as fair-faced concrete furniture products, fair-faced concrete products in garden landscape and home decoration and other fields of fair-faced concrete are widely used.

Because the fair-faced concrete is poured and formed at one time without any secondary decoration, its environmental protection and durability and safety can be guaranteed, and the fair-faced concrete formed by the mold can be made into a variety of products, which makes the application field of fair-faced concrete more extensive. Sen Heng.

Fair-faced concrete has a wide range of applications.
