How long does it take to apply water to the concrete floor?

The newly beaten cement floor, in order to prevent the concrete from losing water too quickly, is to be watered and maintained. In the summer, it needs to be maintained after 4 to 6 hours (mainly to cool down), and from late March to late April and from August to November, it needs to be maintained after 12 or 24 hours.

If the thickness reaches more than five centimeters, you need to water for two more days, which is five days.

The newly paved cement floor should generally 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 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 cement floor is generally watered for 8 hours. If it is in direct sunlight and it is summer, it is generally possible to sprinkle water in about 3-5 hours. If it is a shady place indoors, it is recommended to sprinkle water for about 8 hours, and keep it for 3-5 days without stepping on the ground.

Cement curing watering is generally a few days, more than 7 days, the specific curing time should be determined according to the growth of its compressive strength, usually the water curing time in high temperature weather should not be less than 14 days; The watering and maintenance time in low humidity weather should not be less than 21 days, of which the maintenance of the first 7 days is the most important. For different seasons, the frequency of water maintenance will be different, such as summer high temperature weather, should be watered once every 4 6 hours; In other seasons, 12 24 hours can be watered.

If the cement floor is a big sun, it will lose water once in more than ten minutes.

The frequency of cement curing varies depending on the season, such as summerHot weather, should be watered every 4 to 6 hours; In other seasons, 12 24 hours can be watered.

Watering the concrete floor is for hydration, which can make the concrete ingredients tightly bound together after the plate is released; It can also play a role in heat dissipation and avoid cracks inside the concrete caused by excessive temperature.

Cement curing and watering is generally more than 7 days, and the specific curing time should be based on its compressive strength.

growth situation. Usually the time of watering and maintenance in high temperature weather should not be less than 14 days, and the time of watering and maintenance in low humidity weather should not be less than 21 days, of which the maintenance of the first 7 days is more important, and maintenance measures should be taken to avoid affecting the construction effect.

The number of days of sprinkling water on the freshly paved cement pavement

1. The cement that has just been laid basically begins to solidify after 24 hours, and the sprinkling time needs to be maintained for about 4 to 5 days. If the temperature is relatively high, this time can be extended to a week, and it is necessary to sprinkle water every day, up to several times a day.

2. If the current temperature is relatively high, every other.

One or two hours to sprinkle water again, to repeat many times a day, in order to effectively prevent the concrete surface cracking, in short, to keep the cement floor dry.

3. At the same time, you can't walk on it, and you can basically walk normally after sprinkling water for a day.

The cement floor needs to be watered for about 3-5 days, if the climate temperature is relatively high, it can be extended for a few days, and it needs to be watered once every few hours, so that the cement floor can be effectively avoided from cracking, in short, the cement floor should not be dry.

Usually after the cement pouring is completed, it should be moisturized and cured, ordinary Portland cement can be cured for 7 days, and if it is cement with retarder and penetrant, it needs to be cured for 14 days. If the temperature is below 5 and water is not allowed, we can cover the cement with a cloth to ensure the temperature above and reduce water loss.

Precautions for cement floor construction:1. During the construction of cement floor, it is necessary to pay attention to the problems of hollowing and cracking.

2. The cement floor can not have sanding and other problems, to keep the base surface clean, if there is sanding, it needs to be reprocessed with sanding treatment agent.

3. The cement floor must be kept flat and cannot be uneven.

4. The base surface must be kept dry, and during construction, it can be measured with a test instrument first.

It usually takes 3-5 days for the concrete floor to dry, and about a week if the weather is wet.

The cement setting time is divided into initial setting and final setting. When the concrete first loses plasticity, it is called initial setting, and when the concrete completely loses plasticity, it is called final setting. Generally speaking, the setting time of concrete is related to the setting time of cement.

For ordinary cement, the initial setting is not less than 45min, and the final setting is not later than 10h. Concrete is about the same.

However, today's concrete is often mixed with some mixtures and admixtures, which will affect the normal setting time, especially admixtures. There are many varieties of concrete admixtures, such as coagulants and quick-setting agents, etc., which can extend or shorten the setting time.

After the pouring is completed, under the current winter climate conditions, it takes about 4 days for the cement to reach the strength that people can walk up and move, the indoor temperature cannot be lower than 5 °C, and it takes at least 20 days to completely dry for a month.

One minute, one month, generally 4 days.

Generally, the cement floor can be used after 7 days of maintenance after grinding. Generally, the concrete should be moisturized and cured and covered within 12 hours after pouring, curing time: the concrete mixed with Portland cement, ordinary Portland cement or slag Portland cement shall not be less than 7 days, and the concrete mixed with retarding admixtures or impermeability requirements shall not be less than 14 days, the number of watering times should be able to keep the concrete in a wet state, and the curing water should be the same as the mixing water

If the average temperature of the day is lower than 5 degrees Celsius, do not water. Cover the cured concrete with plastic sheeting, and the entire exposed surface should be tightly covered, and condensation should be kept inside the plastic sheeting.

In summer, the weather is hot and the water is depleted quickly. Freshly made concrete floors should be watered for at least five days. Watering should be diligent, if the water is less, the cement floor is easy to crack.

1. Selection of curing method: maintenance should be started immediately after the concrete floor is paved. All kinds of concrete floors paved by mechanical paving should be cured by spraying curing agents and moisturizing and covering them.

In rainy days or in the case of sufficient maintenance water, it can also be covered with moisturizing film, geofelt, and geotextile.

Sacks, straw bags, straw curtains and other sprinkler wet maintenance methods. It is not advisable to use the enclosed water maintenance method.

2. Cement water storage maintenance and soaking, using mud or mortar around the perimeter of the concrete floor can form a pool. To prevent water loss from concrete, water storage curing is an ideal method and is also effective in keeping the temperature of concrete uniform. The temperature deficit of the curing water should not be lower than that of the concrete floor 11 to prevent thermal stress.

Causing cracks. <>

3. Cement spray and sprinkler curing, when the outside temperature is higher than the freezing point and the humidity is low, spray curing and sprinkling curing are good maintenance methods.

4. Cover plastic film for curing.

The initial time of curing the plastic film is based on the non-crushing mesoscopic anti-slip structure. The thickness of the film should be appropriate, and the width should be greater than the coverage of 600mm.

5. Cover the maintenance of the locust cover.

It is advisable to use moisturizing film, geofelt, geotextile, sack, straw bag, straw curtain and other mulches to moisturize and maintain and sprinkle water in time to keep the concrete surface in a wet state, and thus determine the number of times of sprinkling water every day.

6. Raise Kaidan care time.

The curing time should be based on the compressive strength of the concrete floor.

Depending on the growth situation, it should not be less than 80% of the design compressive strength, and special attention should be paid to the moisturizing and thermal insulation maintenance in the first 7 days. The general number of maintenance days should be 14-21 days, high temperature weather.

It should not be less than 14 days, and the weather with low humidity should not be less than 21 days. The concrete ground mixed with fly ash should be cured, and the shortest time should not be less than 28 days, and the low temperature days should be appropriately extended.
