Why do you need to cover the film after beating concrete?

After the concrete is poured, a layer of plastic film is applied for water retention and maintenance. Because after the concrete is poured for a certain period of time, it needs to be sprinkled for curing, and after pasting a layer of plastic film, the moisture inside the concrete cannot evaporate and remains inside the concrete, providing moisture for the curing behind the concrete. In this way, the number of manual sprinkling and curing can be reduced, labor is used, and the concrete can be cured in time.

Film covering can effectively isolate the moisture on the surface of the concrete from the atmosphere and reduce the evaporation of water, and the film covering can fully react with the cement in the concrete and reduce the internal stress caused by insufficient moisture in the hydration process.

and the early cracks that produce concrete.

The covering time should be covered with the film when there is water after the concrete surface is vibrate, and the film can be better covered on the concrete surface after the water is absorbed by the concrete, and the film will be lifted and the water will be removed after the film is covered for 12 hours, so as to ensure that the concrete remains wet, and the curing time is 7 14 days.

If the surrounding environment does not exist for such conditions, the concrete needs to be cured manually. Concrete curing.

The methods are: 1. The former is covered with a straw curtain and other concrete, and often sprinkled with water to keep it moist. The curing time depends on the cement type, such as ordinary Portland cement.

concrete not less than 7 days and nights.

2. The latter is suitable for high-rise structures and large-area concrete structures that are not easy to be cured by sprinkling, etc., and the perchloroethylene resin plastic solution is sprayed on the surface of the concrete with a spray gun, and a thin film is formed on the surface of the concrete after the solution volatilizes, isolating the concrete from the air, preventing the evaporation of water in the concrete to ensure the normal hydration of the cement, and the film can age and fall off by itself after the curing is completed.

So finish beating the concrete.

The covering film has two functions, the first is to prevent water loss and play a role in maintaining health, and the second is to protect the surface of the concrete from wind, especially in summer.

Crack. Therefore, we see that as long as the concrete is finished, a layer of film is pasted, so that the concrete will not be damaged after drying.

After the concrete covering film is a way to curing concrete, after the film is covered, the concrete can reduce the evaporation of water vapor, do not need to water frequently, and can reduce part of the labor.

First, the concrete structure is relatively rough and built for the sake of beauty; Second, if you don't cover the film, there are more potholes and potholes, which is not easy to clean.

Covering the concrete with a layer of film can prevent the concrete from becoming rough, which is to make the concrete smooth.

The main purpose is to prevent oxidation, carbonization, the external temperature of the concrete is not the same as the internal temperature, and it is easy to crack and deform.

Prevent moisture loss and cause cracking, and really help you look forward to it

If the water evaporates too quickly, it will affect the firmness of the concrete.

Summary. Dear, hello, I'm glad to answer for you, can concrete cover film in summer? A: First of all, it must be explained that concrete can be cured with film cover in summer.

Can concrete be covered with film in summer?

Dear, hello, I'm glad to answer for you, can concrete cover film in summer? A: First of all, it must be explained that concrete can be cured with film cover in summer.

It is very necessary to pour the concrete cover film in summer, which can prevent the rapid evaporation of water and make the concrete crack, but the temperature is high, the concrete hydration reaction is fast, and the water in the film is also absorbed quickly, but it will not crack.

If you want to ensure the humidity in the concrete, you need to cover the plastic film after sprinkling curing, and it is a very good curing method to maintain the moisture in the concrete through the sealing of the plastic film.

Can the film be covered in a hot weather of 35 degrees?

In summer, do you still need mulch film to grow vegetables in hot weather? The correct answer is "needed". First of all, the temperature is relatively high in summer, and we can use plastic film to suppress the surface temperature and prevent the surface temperature from being too high, which affects the growth of plants.

Different colors of mulch film correspond to different effects, in the summer we can use black mulch film that can absorb heat, so as to ensure the normal growth environment of crops. Secondly, it can effectively prevent water evaporation. As we all know, water is also very important for plant growth, and in summer, the water in the soil is evaporated, and crops often die due to lack of moisture.

In hot weather, watering the vegetable patch at any time is also quite a painful errand, at this time the mulch film can play its important role, because the mulch film can avoid direct sunlight on the earth, can prevent the water from evaporating, so as to preserve the necessary water for plants in the soil. It can be seen that when planting vegetables in summer, mulch film is also a good helper to increase yield. However, there are also many farmers who have reported that the yield of plastic film has indeed increased in the first few years, and the longer the time, the effect has deteriorated.

The film covering the poured concrete can be torn off after 3 days.

Generally, there are two kinds of cover films, and there are more anti-cracking when pouring roof concrete; In addition, in order to prevent the insulation from sticking to the concrete during winter construction, a film is first laid.

In the first case, if it can be more than 3 days, the anti-cracking effect of concrete will be better, but with the current weather conditions, for the construction progress, such as pay-off, maintenance, construction and the need to clean up the film (it is not easy to clean up after a long time), many construction sites will tear off before the next day.

This is the contradiction between quality and construction schedule, as long as the quality is met, the construction method and so on should try to meet the requirements of the schedule.

The second type is torn off when the weather improves.

Now it has not come according to the requirements, and the construction period requirements cannot be met, and it is generally torn off after the initial setting for the pay-off and feeding.

Generally, when this noodle is used, it should be used after a week.

At least three days to allow the concrete surface to reach a certain strength.

If there is a cold and windy weather, it should also be covered with other insulation layers.

Summary. The covering film can be used to make the moisture of the concrete not easy to lose, and it has a thermal insulation effect, which will be implemented after the construction is completed. At low temperatures, the film can also prevent icing during the curing period.

Isn't it better to cover the concrete with a film after pouring.

Yes dear. 1.The covering film can be used to make the moisture of the concrete not easy to lose, and it has a thermal insulation effect, which will be implemented after the construction is completed. At low temperatures, the film can also prevent icing during the curing period.

2.Disadvantages: Relatively speaking, it is more troublesome to operate, with an additional process and high cost

All right. Is the film covered immediately after the concrete has been poured?

You can change it if you pave it first. Cover.

Summary. Dear, hello, I am glad to answer for you: Is it reasonable to tear off the film and then water it after 12 hours after the concrete is poured in summer?

Answer: in the summer, after the concrete is poured, the film is torn off and then watered reasonably, and it is very necessary to pour the concrete cover film curing in summer, which can prevent the rapid evaporation of water and make the concrete crack, but the temperature is high, the concrete hydration reaction is fast, and the water in the film is also absorbed quickly but will not crack, at this time, the film should be torn off in time for watering and curing, and the general cover film is to cover the film while pouring concrete, and sprinkle some water on the surface when closing the surface. It can ensure that the film cover is not easy to be blown up by the wind, and it can also make the film have enough moisture under it to ensure the hydration reaction, the general time to tear off the film is the final setting time of the concrete, and it also depends on the weather and temperature.

Thanks, I'll wait.

Hello summer concrete can be covered with film, summer such a high temperature season, concrete can be covered with plastic film rough maintenance, in addition to the high temperature season cover when the wheel bench fiber is relatively short, before the cover needs to wipe the concrete wax imitation surface of the plastering treatment, other operation methods and normal maintenance is not much different, there is also a point worth paying attention to is the time, generally in the summer film covering time should not be too long, to 24 hours is the most appropriate, When the time comes, the film is uncovered and then watered and cured normally. Hello dear to me, I hope it can help you, thank you for your trust, I wish you a happy life!

If there is no need to use it immediately, it is better to cover it immediately, but it should be covered completely, and it will be covered after the completion of the closing surface, and it will have no effect if it is late. Because cement curing requires proper moisture, it must react with moisture in order to continuously increase the hardness of concrete. Cover with plastic film to prevent moisture from evaporating.

If the water evaporates too quickly, it will affect the curing of the concrete, resulting in dry cracking, peeling and other phenomena, which will affect the strength of the concrete.

A kind of special cast-in-place concrete curing of the production of aura. With the new controllable polymer absorbing material as the core raw material, it is developed according to the hydration principle of concrete. The core material has a special functional group, which can absorb hundreds to thousands of times the weight of water, and form a miniature small reservoir after absorbing water.

However, it can transmit and penetrate on the surface of the concrete with the capillary phenomenon, continuously provide concrete health water, and repeatedly absorb the evaporated water of the health body, so although the water is only watered once during the health care period, the health body can always keep more than 90% moist.
