How to deal with the sand on the cement floor, how to deal with the sand on the cement floor

The cost of cement floor is low, and many roads and factories will lay cement floors, but the cement floor is prone to problems such as sand and peeling in the later stage, which affects the service life of the ground. So how to repair and maintain the situation of sand on the cement floor? Next, I will briefly introduce to you how to deal with the sand on the cement floor.

1. First of all, we need to clean the cement sanding floor, and then repair the cement sanding floor. If the sanding area is small and not serious, you can mix the cement mortar well and apply it to the sanding position. If the sand area is large, it can be repaired with a ground treatment agent.

We first apply the interface agent evenly, then apply the repair mortar, and finally cure and polish the floor.

2. There are many reasons for sand on the cement floor, such as incorrect cement mortar ratio, poor quality of cement sand, etc. We should configure cement mortar in strict accordance with the construction requirements, and cannot use agglomerated cement; The cement mortar should be stirred evenly, and uneven mixing is prone to the problem of sand peeling. The construction personnel should grasp the calendering time, and calendering the ground too early or too late is prone to sand problems.

3. The sanding of the cement floor may also be caused by improper maintenance. Maintenance is required within 12 hours after the cement floor is poured, and the general curing time is two to three weeks, and the specific curing time is determined according to the local weather conditions. The cement floor is mainly covered with moisturizing film sprinkled water maintenance, the moisturizing film should completely cover the ground, and the water should be sprinkled in time every day, and the cement floor should be in a wet state.

How to deal with sand on the cement floor.

1. If the sand at home is not very serious, you can use glue cement paint to fill 2. Use a professional mud ground sand treatment agent, which is a kind of construction glue.

3. This method is the most effective, of course, the most troublesome, that is, to completely remove the cement layer of sanding, and then make a new cement layer.

4. This method has limitations, that is, the cement floor is cleaned and laid on the wooden floor.

Cement concrete pavement is exposed to sunlight, rainwater, freeze-thaw and various chemical erosion in the natural environment for a long time, and the impact load, cyclic load and abrasion of the vehicle will cause surface damage such as sand and peeling, exposing bones, and fine cracks on the road surface as shown below

Cement concrete road is only the appearance of sanding, peeling, exposing and other surface damage problems, but the foundation and strength are relatively stable, if the traditional repair method is adopted, the whole needs to be knocked off and then poured again, this process has a long construction period, high cost, pollutes the environment, serious waste of resources, and the disadvantages are more prominent.

How to deal with sand on cement pavement? What can be remedied? Is there a more cost-effective way to deal with it?

Huineng new technology materials can accurately repair the location of diseases, and cement pavement repair materials have been widely used because of their good bonding properties, compression and wear resistance, waterproof and frost resistance. The use of cement pavement repair material to repair and treat road diseases effectively reduces the cost and cost of the project, the construction is convenient and fast, the traffic is restored within 2 hours, the traffic congestion is solved, and the public is convenient to travel.

1. Ground treatment

First of all, the loose parts of the drumming, peeling, cracks and other parts are removed, and the parts below 3mm and the oily parts should be brushed, and the brushing method can be struck with a professional milling machine or manually with a sharp hammer. After ground treatment, wash with a water gun to fully moisten the working surface until there is no more water seepage.

2. Stir the material

Add water: mix the material with water (non-polluted water), stir evenly when stirring, stirring time is about 3 minutes, not too long, to prevent solidification in the mixing barrel.

3. Repair and pavement

For the repair of small pits, hemp surface, peeling, exposed, fine cracks, etc., pour the stirred material on the working surface and flatten it with a larger trowel (no secondary plastering). The initial setting time of the material is short, and there will be adhesion during the initial setting, which is not conducive to smoothing, so first use a scraper to pave a large area and then use an iron trowel to level and collect the light.

4. Health and traffic control

After the final setting, the sprinkling water cover is carried out, and when the temperature is above 20, it can be opened to traffic in 1-2 hours; When the temperature is low, the opening hours can be extended appropriately.

Hello, I am honored to answer this question for you, 1. It is best to deal with the situation of small area of sanding, you can smear some cement slurry on the ground of sanding, and so on, the ground will have some color, but it is not a big problem to use.

At this time, the method of plastering mortar is ineffective. It is recommended to use professional materials for treatment, mix the repair mortar with water, apply it to the ground, keep it for more than 3 hours, and finally clean the ground.

1) Special interface agent for rolling coating on the ground.

2) Plaster the ground with universal repair mortar.

To deal with cement floor sanding, you can use Huineng Road and Bridge Sand Lifting Special Rapid Repair Material for thin layer repair.

Construction process: After the road surface is milled, it is washed with clean water, and then 3-5mm repair material is paved, and it can be opened to traffic after 1-2 hours of maintenance.

If it is simple to deal with, you can buy the cement sanding treatment agent of the ground guard, pour the curing agent on the cement floor, and keep it moist for 60 minutes.

How to deal with sand on the cement floor.

To treat the sanding of cement floors, Cronfer concrete sealant can be used. Concrete sealing curing agent is a commonly used material in floor construction, which can effectively improve the hardness, wear resistance and compactness of cement floor.

Through effective penetration, the concrete sealing curing agent will react with the free calcium and magnesium ions in the cement floor to form a hard gel substance, which will turn the originally evacuated ground structure into a dense whole, thereby solving the problem of sand and dust on the ground.

This situation is also relatively simple to deal with, with penetrant and hardener for construction to form a hardened floor, the hardness should reach granite grade 9, so that the phenomenon of sand is not easy to occur. Cement floor sanding is generally because the strength of the concrete is not enough, and then after the use of epoxy or improper ground has been sanded, do not rush to let the decoration workers on the top of the plastering or do concrete cushion to cover the sand layer, that will make the workmanship appear hollow, the floor layer will appear bow convex or from the floor crack to the outside of the dust, but to check, whether the ground has a batch of scraping layer, for the batch of scraping layer and has been cracked hollow, to remove; Wear-resistant flooring is caused.

The sanding treatment method of cement floor is as follows:

Tools Raw materials: brushes, fine hair brooms, small and pure portable spray guns, pavement repair materials, mixing buckets, electric drill mixers, large spatulas, small putty shovels and other tools and materials.

1. Before repairing, check the sand on the road surface and prepare the required materials.

2. Use a brush and a fine broom to clean up the dust and debris on the surface of the base layer until the surface layer is exposed. After that, rinse it with a large amount of water, and then use a small portable spray gun to carefully rinse it to ensure that the base layer is free of any floating ash and debris, which can make the cement pavement more durable and stable.

3. This step is very important, first use a fine hair broom to sweep out the visible water on the base layer, and then let the surface of the base layer soak for about 20 minutes, which can make the road surface more active. Note that there should be no open water on the surface of the base cherry tree to avoid affecting the stability and adhesion of the material.

4. Pour the prepared repair materials into the mixing barrel, add 4kg of water to each bag, and then use the electric drill mixer for more than a minute until it is completely uniform and free of particles. Note that when stirring, you must stir sufficiently, otherwise it is easy to have problems such as particles.

5. Yuyun Cong poured the stirred materials into the pavement base, immediately paved it quickly with a large spatula, and then scraped it with a small putty shovel to make the surface of the base layer more flat. In addition, after the application is completed, it is necessary to carry out watering and maintenance within a day, and during this period, it is necessary to do a good job of marking, and no pedestrians or vehicles should pass through, which will affect the aesthetics and flatness of the road surface.

Cement floor sanding can be sanded, painted with floor paint, applied with cement slurry, and so on.

1. Grinding. First of all, use a grinding machine on the ground to polish all the sanding parts on it. The standard for passing the polishing is to expose the ground stones, sand, and no loose cement mortar.

And it presents a certain brightness, after which you can proceed to the next step of construction.

2. Paint the floor.

To apply floor paint, the first thing to brush is the primer. Because the primer seals and solidifies the original ground, the primer should be applied in place. After that, it's time to apply the epoxy floor paint.

Generally, epoxy floor paints are self-leveling and non-self-leveling. Either way, it's basically done in two passes, so the ground is done.

3. Apply cement slurry.

At this time, do not use pure cement slurry, you can add some clean fine sand to the cement slurry. When applying, the thickness must be controlled, and try to control it at two or three millimeters. Apply it again and again, and calender it with an iron spike and trowel.

One thing you must pay attention to is that you must sprinkle the original ground with water to moisten it before applying. This will allow the mud to be smeared and a new concrete floor will be formed.

Cement floor maintenance method:

1. Selection of maintenance methods. Cement floor maintenance is very important, maintain it immediately after completion, it is best to spray some maintenance agent on the ground while moisturizing it. In case of rain, you can lay some sacks or straw bags on the ground to prevent rain from washing the ground.

2. Cover with plastic film for maintenance. Plastic film can also be used to maintain cement pavement. Pay attention to the thickness when choosing the film, the coverage width is generally 600mm, only more than that, in order to ensure that the ground is covered.

3. Cement water storage maintenance and soaking. Cement floors can also be cured by water storage and soaking, forming pools with mortar, surrounding the ground, and preventing water loss. However, the temperature of the curing water should not be lower than 11 to prevent cracks in the ground.

4. Maintenance time. When maintaining the cement floor, it is necessary to grasp the time, mainly to see the compressive strength of the ground, which cannot be less than 80 of the compressive strength. The cement floor should be maintained in early stages, generally for about half a month.

If the weather is hot or humid, the number of maintenance days should not be less than 20 days.

Sand formation on cement floors is a common problem that requires different treatment methods depending on the severity.

1. Remove the surface ash, carefully observe the severity of the cement floor grinding in the house, and take different treatment methods according to the severity.

2. If the grinding area of the cement floor is small and the floating sand is small, it is recommended to use pure cement slurry to cover the surface. Cement can be made from regular Portland cement.

3. If the cement floor area is large but the sand is not very serious, it is recommended to use a professional ground treatment agent, which is simple to use but has obvious effects.

4. If the sand on the cement floor is very serious, it is recommended to repair it, remove the original surface layer and re-lay the surface layer. Relaying the surface layer is equivalent to rebuilding. Precautions during construction are also precautions for sanding on concrete floors.

This is so important that it will be listed separately.

There are many rural homes touching cherry blossom garden in the decoration, the ground on the first floor is still mainly paved with cement, but this kind of cement has been used for a long time, and it is easy to sand after wear, which is an unavoidable problem, once the sand is raised, it will become more and more serious, so most people will choose to repair it in time, what is the cause of the cement floor sanding? How to deal with the sand on the cement floor? Xiaqiao Humian will follow the experts of Qeeka Home to find out.

1. How to deal with sand on the cement floor.

The sand area is small, and some pure cement slurry can be deployed and smeared on the sand area for repair; The sand area is large, and it is necessary to use a professional ground treatment agent, which can be repaired after mixing and diluting with water. If the sand area is large, it is necessary to apply all the interface agent, then pave and repair with universal repair mortar, and finally solidify and polish the ground.

2. What is the cause of sanding on the cement floor?

1. Improper material allocation.

According to Qeeka Home experts, material allocation can be said to be the key to sanding, once the proportion of cement materials, lime materials or water is not appropriate, it is easy to sand after construction, especially the amount of water must not be too large, it needs to be controlled between 15-20%, you can be sensitive to stop while adding water while mixing and stirring, adding water at 17% to stop and observe to avoid adding too much water at once.

2. The quality of the material is not good.

There is also a major reason for the sand of cement floor, especially if there is a problem with the quality of cement and lime, whether it is the use of unqualified cement, or the use of unqualified lime will be sanded, and the cement is best to choose Portland cement with high early strength, if ordinary Portland cement is used, it is easy to premature agglomeration, moisture agglomeration and other problems.

Summary: The above is about how to deal with cement floor sanding, and what is the cause of cement floor sanding, I hope the content shared can give you some reference, if you want to know more about relevant knowledge, you can **** Qijia Home to consult.
