Can there be water for a long time if the cement floor is done for 24 hours?

Like the cement floor, within 24 hours after it is done, it is true that there can not be water for a long time, once there is water for a long time, it is likely to be damaged, but this is also according to the standard of the cement.

Can there be water for a long time if the cement floor is done for 24 hours? The good cement floor can not have water for a long time, which will lead to the cement floor is not insisted on and is not strong.

There should not be water within 24 hours after the cement floor is done, and you can sprinkle some water for health after a day.

The cement floor is done for 24 hours, I think there can be water for a long time, there is nothing wrong with this, as long as it is solidified, it is not a problem.

The concrete floor was done for 24 hours. The long-term presence of water proves that the degree of mercury draft is not good, so the cement floor must be allowed to eat water.

Based on your description, this scenario is okay. After the final setting of the cement floor, it can be cured with water, so that the cement will not crack easily.

Hope mine is helpful to you.

The concrete floor is done for 24 hours, this should be able to have water for a long time, this should be the one that can make them more practical, and he should be able to make him more stable.

Can the cement floor be used for a long time for 24 hours? It is generally not possible to use water for a long time on a concrete floor, but it is okay to use water.

If there is water for a long time, it can help the solidification and shelf life of cement, which is of course a good way.

This is possible, and it is a completely problematic habit that can help.

After six hours of plastering the cement, there is no fear of rain, and the more it rains, the stronger it gets. However, if there is no rain after the cement is paved, it is necessary to carry out manual water splashing for more than seven days, and it is necessary to splash about three times a day.

After the cement floor is paved, the curing time should be determined according to the condition of the growth of the compressive strength of the concrete floor, generally not less than 80% of the design compressive strength, and pay attention to the maintenance of the first seven days when curing the cement floor, usually 14 days of maintenance in high temperature weather, and 21 days in low temperature weather.

Choice of maintenance method

We all know that the concrete floor building must be cured immediately after completion, and the various concrete floors laid by machinery must be sprayed with curing agents, and the method of moisturizing cover must be used for maintenance. In rainy days, you can also use maintenance methods such as moisturizing film, straw bags, sacks, and straw curtains, but you must not use maintenance methods such as water.

After the cement floor is paved, the curing time should be determined according to the growth of the compressive strength of the concrete floor, which is generally not less than 80% of the design compressive strength, and the maintenance of the cement floor should be paid attention to the first seven days of maintenance.

Cement for 6 hours is not afraid of water.

The cement is not afraid of rain after 6 hours. After 6 hours, if it rains, the more it rains, the more solid it will be. However, if it rains before it is completely solidified in the first 6 hours, it will affect the strength of the cement.

In fact, after pouring cement, an appropriate amount of water is needed for maintenance, especially in the case of hot weather, the temperature is relatively high, and the frequency of watering needs to be increased. You can pour more in the first two days, but you can slowly reduce it in the next few days, which also changes according to the change in the strength of the cement.

Why concrete should be watered and cured

1. After pouring concrete, the curing process is relatively long. Because it has a great impact on the quality of the concrete, after the concrete is successfully poured, the hardening and strength will continue to increase, mainly because the cement has been hydrated.

2. The occurrence of hydration needs to be under a certain temperature and humidity environment, and it is necessary to carry out reasonable maintenance by artificially and artificially create certain temperature and humidity conditions, so as to make the strength of cement continue to grow and achieve the required effect.

3. In order to ensure the strength of concrete.

Also in order to avoid the phenomenon of cracking on the surface of the concrete, watering is the most reasonable way, after pouring 12 hours at room temperature, you can continue to pour water in the cavity, and the curing period should not be less than 7 days.

4. The reason why it is necessary to keep watering is mainly because the water in the concrete is steamed quickly, which will affect the effect of solidification. If the current temperature is relatively low, below 5, it can not be watered and cured, and it can be covered with film.

Summary. Cement will not burn out if it is not watered for 24 hours. But it still depends on the weather, if the temperature is above 30 degrees, the cement is easy to burn out without watering, and if the temperature is below zero, the cement is easy to freeze.

When the cement water is about 6 to 10 hours after construction, you can spray mist water to do maintenance work, you should know that the concrete will appear in about 4 to 6 hours of final setting, easy to cause surface water loss, so you need to sprinkle mist water to ensure its wetness. Note that ordinary water should not be used to avoid damage to the cement surface by water droplets.

Does the cement affect watering after 24 hours?

Hello, I am your full-time answerer today, and I am happy to answer for you

Does the cement affect watering after 24 hours?

After 24 hours, the concrete surface has compressive strength, then it can be watered for maintenance.

Generally, after calendering for at least 12 hours, or stepping on the traceless sedan car quietly collapsed, and most of the ground was white, it began to sprinkle water for maintenance. After the cement floor is plastered and calendered, it still needs to be sprinkled with water to keep it closed for 3 to 5 days to meet the strength requirements. When the calendering is completed for at least 12 hours, the cement reaches the final setting state, but sprinkling water before 12 hours will re-simmer the surface skin, that is, the phenomenon of segregation.

Generally, after calendering for at least 12 hours, or when there is no trace on the foot, and most of the ground is white, start sprinkling water for maintenance. After the cement floor is plastered and calendered, it still needs to be sprinkled with water for 3 to 5 days to meet the strength requirements. When the calendering is completed for at least 12 hours, the cement reaches the final setting state, but sprinkling water before 12 hours will re-simmer the surface of the earth, that is, the phenomenon of segregation.

Therefore, after 24 hours of Danshan Hui, the cement surface has a compressive strength mold, so it can be watered and maintained.

Cement will not burn out if it is not watered for 24 hours. But the specific need to look at the weather of the oak, if the temperature is above 30 degrees, the cement is not watered is easy to shout burn-resistant, and if the temperature is below zero, the cement is prone to freezing. When the cement water is about 6 to 10 hours after the construction, you can spray mist water to do the maintenance work, you should know that the concrete will appear in about 6 hours from 4 to Zheng Lachun, which is easy to cause water loss on the surface, so it is necessary to sprinkle mist water to ensure that it is wet.

Note that ordinary water should not be used to avoid damage to the cement surface by water droplets.

The above is the answer given. You can refer to it, I hope it will help you. If you are satisfied with my service, I hope you can praise my service and sales. I wish you a happy life and all the best. 

Summary. 1. If it is in direct sunlight and summer, it can be sprinkled in about 3-5 hours. The evaporation of the water contained in the cement can be accelerated by solar irradiation, so it is relatively fast to solidify and dry in this case.

1. If it is in direct sunlight and summer, it can be sprinkled in about 3-5 hours. The evaporation of the water contained in the cement can be accelerated by solar irradiation, so it is relatively fast to solidify and dry in this case.

2. If it is a cool place indoors, it is recommended to sprinkle water for about 8 hours, and keep it for 3-5 days and do not step on the ground until the cement is completely dry.

3. If it is a rainy day or a relatively humid weather, then you need to wait for 2-3 days before you can sprinkle water, because the cement contains more water in the cool weather, and it is not easy to dry it completely. How do you level a concrete floor? 1. If the ground is uneven, you can use cement mortar to smooth it, and it should be noted that the cement needs to be mixed with sand, otherwise it is easy to crack in the later stage.

2. Using a grinding machine to polish the uneven area of the cement floor, the previous rough cement floor can become smoother.

Hello, in the case of cement, if it is not watered within 24 hours, it will not cause it to burn out. However, if the cement surface is too dry during the initial stage of cement solidification (approximately 24 hours), it may cause cracks or cracks to appear on the surface, a process known as "dry shrinkage". This will not completely destroy the cement or render it unusable, but it will reduce the strength and durability of the cement.

In this case, the best way to protect the cement from drying damage is to keep the slag-based surface wet. In order to overcome the problem of shrinkage, the right amount of watering can be carried out on the first day after pouring the cement. However, overwatering can also lead to cement weakening and cracks.

Therefore, the amount of watering should be controlled as needed to maintain sufficient humidity on the cement surface and avoid allowing it to dry.

Generally, it should be sprayed with mist water after 6 10 hours for curing, because the concrete has reached the final setting in 4 6 hours, the concrete loses fluidity and surface water, and it should be kept moist in time. Only spray mist water on the first day to prevent water droplets from damaging the surface.

After the cement solidifies, it needs to be watered for more than 3 days. Depending on the weather temperature, it should be maintained for at least 3 days in spring and summer, and the normal one is a week. In autumn and winter, especially in winter, it is best to avoid direct watering and contact with the cement surface, and it is best to water on the film after covering it, and maintain it for about a week.

The role of watering actually boils down to hydration. Hydration is a chemical reaction.

It allows the various ingredients of concrete to react and tightly combine to meet the strength requirements. Theoretically, the wetter the place, the longer the time, the higher the strength of the concrete.

After three or four hours, you can water. After the cement solidifies, it needs to be watered for more than 3 days. 7 days from the 3rd basement to the basement mezzanine roof, and 14 days for the 1st basement roof. After the concrete surface is pressed and wiped twice, it is covered and raised in time.

How long it takes for a concrete floor to be watered depends on a number of factors, including the mix ratio of the cement concrete, ambient temperature, humidity, and wind speed. Generally speaking, it takes a certain amount of time for the cement floor to pass through water after pouring to ensure that the concrete is fully hardened and the strength meets the requirements.

At a normal temperature (around 20 °), it is generally necessary to wait about 28 days for the water to be connected. However, in the hot season or in a dry environment, the hardening rate of concrete will be accelerated, which may shorten the water flow time; In the low temperature season or in a humid environment, the hardening rate of concrete will be slower, and it may take longer to pass the slag water.

Therefore, a reasonable construction plan should be formulated according to the specific situation before construction, and cured according to the requirements after pouring to ensure that the concrete is fully hardened and the strength meets the requirements.
