What are some good ways to prevent sand from rising on the concrete floor?

If the sand in the house is severe, in this case you can choose a universal method of repairing the mortar, which is very simple. You only need to sand the mortar on the ground, and after sanding, you can do some curing treatment, and the ground will become very shiny, and such a material is also durable.

If you have shark sand on the ground at home, don't worry. Now there are many products on the market to repair the ground, and this universal repair mortar can quickly repair the ground with very good results. Generally speaking, the most convenient way to get out of the sand is to re-brush the grout, sometimes there is only a little sand in the area, so you can only brush this place and make up a small part.

The newly brushed grout, although very deep, will gradually change to the same color as it dries over the next few days.

Then there is the emergence of large-scale grinding, which needs to be repaired on a large scale. If necessary, brush a layer of interface agent first, and then use cement slurry. The grout can be thinner for easy flow and trowelting.

However, it is recommended that professional masters do it, because the cement floor is not easy to smooth and requires professional technology, otherwise some places are high and some places are low, and it is easy to accumulate water.

The other option is not bad, but this one may not be suitable for outdoor environments. Indoor cement floors can be used, that is, they can be repaired with self-leveling. This one does not require cement slurry, and the floor is cement colored, but it is clean and smooth, and has a clear feeling.

It's good, but the cost is relatively high. You can check with your local ** and decide whether to use it or not.

Of course, speaking of this, many friends will still ask if there is a way to reduce sand. In fact, there are many reasons for sand. For example, this original ground laying problem, whether there is a heavy object rolling is the reason, and then there is water on the ground in winter.

If the water freezes at low temperatures, it will crack the concrete floor, so we should be careful. Whether it is outdoor or indoors, do not leave standing water on the ground in winter, and clean it in time.

The water-cement ratio is too small, resulting in a large amount of cement, a harder mortar, difficult construction, and damage to the surface strength. The water-cement ratio is too large. In order to enhance the workability of the mixture, the water-cement ratio is increased at will, resulting in too little cement, water leakage on the surface, reduced mortar strength, no wear resistance on the surface, and loose cement ash and sand scattering after walking on the surface.

At this time, we should pay attention to the ratio between cement and water, be sure to remove all the surface drawings, if the mud situation is not serious, you can choose the local treatment method, if it is particularly serious, you must re-lay the cement. Pay attention to daily care.

The better way is to cover it with some mesh gauze, build some houses around, cover the cement floor, protect the cement floor, or intercept it through some items.

You can choose to sprinkle some water on the cement floor, or you can use cement glue to prevent the cement from getting sandy, and you should usually clean it more, and the effect is very good.

It can be filled with cement, or it can be reprocessed. Do not use sharp objects. Try not to let the sun shine and water it properly.

If the sand area is small, you can mix some pure cement slurry and apply it to the sand area for repair. If the sand area is large, you need to use a professional ground treatment agent, mix and dilute with water, and then apply it to repair. If the sand area is large, the repair is a little more complicated, and it is necessary to apply all the interface agent, then pave and repair with universal repair mortar, and finally solidify and polish the ground.

1.Strictly control the water-cement ratio of cement mortar.

The size of the water-cement ratio is an important factor that directly affects the strength of the mortar. If the water-cement ratio is too large, the strength of the ground will be low, the surface of the ground will be rough and not wear-resistant, and it will be easy to sand. In addition, too much moisture on the surface will prolong the calendering time of the surface layer, which may exceed the final setting time of the cement, and naturally the quality of the ground cannot be guaranteed.

On the contrary, if the water-cement ratio is too small, it means that there is too much cement, the mortar is dry and hard, the construction operation is difficult, the dry shrinkage is large, and the ground is prone to cracks, which also affects the quality.

2.It is forbidden to use expired cement and damp cement.

Cement stored for more than 3 months is called expired cement. Expired cement will react with water vapor and carbon dioxide in the air, and the calcium carbonate generated will weaken the cementing properties of cement and reduce the heat of hydration. Therefore, when expired cement is used in the ground surface layer, its strength, hardness and wear resistance will be significantly reduced, resulting in sanding.

3.Adequate curing time should be allowed.

The quality of conservation work is closely related to the quality of the ground. After the cement mortar is mixed, it is from the initial setting to the final setting, and then enters the hardening. After hardening, the hydration will continue to penetrate deep into the cement particles in a humid environment, and the strength of the mortar will continue to increase.

Generally, 7 to 14 days and nights of maintenance time should be applied. If the curing time is insufficient, the water will continue to evaporate in the dry air, which will slow down or even stop hardening, and the surface mortar will not be able to reach the design strength, and then problems such as peeling or sand exposure will occur, and sand will inevitably rise.

If the cement floor is sandy, we had better lay the ground with bricks, so that the cement floor will not be sandy, and the cement floor can also be polished.

I think the best thing to do is to spray the hardener on the concrete floor, so that there is no pulverization and sanding.

1.To remove the floating ash on the surface, different treatment methods should be implemented according to the degree of cement sanding. 2.

If the area of cement floor sand is less and the floating sand is small, it is recommended to use pure cement slurry for local covering, and ordinary Portland cement or Portland cement can be used for cement. Strictly control the water-cement ratio of cement mortar: the water-cement ratio is an important factor affecting the strength of the mortar.

If the proportion is too large, the strength of the ground will decrease, the surface will be rough, and the sand will rise easily. If the water-cement ratio is too small, the mortar will dry out and the ground will be prone to cracks.

A small part of the area of sanding, encountered a small part of the area of sanding, generally not a big problem, in the sand place to smear a layer of cement slurry, and so dry after the ground looks back to have some color, as long as grinding for a period of time, the color is basically the same as the old.

Half of the area of sand, if a ground is close to the general area of sand, this kind of mortar will not be used bad luck, then it is necessary to use professional repair materials to deal with, repair mortar and water stirring Zheng Chun, smeared on the ground, after 3 hours of drying, you can walk around.

Most of the area of sanding and most of the area of sanding, the use of ordinary repair mortar will not work, must use universal repair mortar, the specific method is as follows. Pour the interface agent on the ground that needs to be repaired, and do a good job of base treatment. Then pour the all-purpose repair mortar and throw it flat with a special tool.

In order to make the ground shiny, more beautiful, and more durable, it is recommended to do the fixed phone treatment, so that the ground is bright and new.

Sand on the cement floor, a small part of the area of sand is smeared with a layer of cement slurry in the place where the sand is raised; Half of the area is sanded, and professional repair materials need to be applied; If it is a large area of sand, it needs to be cracked quietly and treated with universal repair mortar.

In the decoration process, sand on the bottom surface of cement is a relatively common situation, which has caused many troubles to our decoration. The reason for the sand on the cement floor is that many people think that it is caused by insufficient cement. In the process of decoration, the ratio of water and sand and gravel is not right, and the cement is too little.

In this way, the cement mortar seeps water and the cement floor is sandy.

The solution to this situation is relatively simple, if the sand at home is not very serious, you can use glue cement paint to fill. The use of professional mud sand treatment agent is a kind of construction glue. This method is effective, but of course troublesome, that is, the sanding cement layer is completely removed, and then the cement layer is made from scratch.

This method has the limitation of cleaning the concrete floor and laying it with a wooden floor.

Causes of sanding on cement floors:

1. Light cement ratio: Simply put, the proportion of water and sand in the process of decoration is too much, and the cement is too little. In this way, the cement mortar will be caused to seepage, which will reduce the strength of the cement floor surface, resulting in the problem of sand on the cement floor.

2. The quality of sand is not good: there are certain quality problems in the cement and lime used in the decoration, and the use of unqualified cement or substandard lime may cause sand on the ground.

3. Improper maintenance: failure to maintain in time or insufficient maintenance in the later stage, exposure to the sun or strong wind leads to a large amount of water loss on the concrete surface, and the surface is not fully hydrated, resulting in a decrease in strength.

Now some of the roads we take are cement roads, and some of the cement pavements on them have been for a long time, or because of improper maintenance, they will cause the phenomenon of sand on the ground. If you leave it alone, it will get worse and worse, and there will be potholes. So what are the solutions to cement floor sanding?

1. Pure cement repair: If the area of sand is relatively small, we use general Portland cement to remedy. Generally, it is used on the roof or yard of your own house, and the cost of this method is relatively low, that is, it is not compressive and wear-resistant.

2. Cement with glue: This method of mixing cement with glue only solves the problem of its surface, although it looks good, but it is not durable. Generally, this is done to cope with the inspection, and we generally do not recommend it.

3. Cement repair mortar: use cement repair mortar for treatment, which can not only solve the problem of sanding, but also be more durable. Generally, it can be used normally in one day, but its cost is relatively high, and the construction is complicated.

4. Cement pavement sanding treatment agent: This is specially designed to solve the problem of sanding on the cement floor, and the strength of the cement floor is fast, which can fundamentally solve the sanding. And it will not change the appearance of the ground, the repair cost is relatively low, and the service life is relatively long.

It is recommended to use some water-based treatment agents or oil-based floor penetration curing agents.

1. Pure cement repair. If the range of ground sand is relatively small, Portland cement can be used to mix the cement into a suitable consistency and then cover the sand place to wait for hardening.

2. Cement glue. Some construction glue can be mixed into the cement, but this method can only solve the problem for a short time, and it will still sand after a long time.

3. Use sand treatment agent. The sand treatment agent can fundamentally solve the problem of cement strength, and the cost is very low, and it can be used for a long time, and the ground sand removal performance is very good.

Cement floors are popular because of their low cost and ease of construction. However, the structure of the cement floor is relatively loose, and it is easy to cause dust and sand, cracking, and even potholes after being used for too long. In particular, dust and sand will lead to an increase in dust particles in the air, and the harm to the human body is self-evident, so how to quickly solve the problems of the cement floor has become particularly important.

Dusty and sandy cement pavement.

1. Portland cement.

The use of Portland cement is directly repaired in the place where the dust and sand are raised, and the cost of this method is low, but the compressive and wear-resistant ability of the cement floor after repair is not very strong, and it is easy to dust and sand again.

Second, the protection of concrete No. 1.

It is repaired with the No. 1 repair material of the protective concrete. This method is easy to construct, and can be opened to traffic within 2-3 hours after the construction is completed, and has good impermeability, freeze-thaw resistance, wear resistance and corrosion resistance.

3. Cement floor hardener.

Cement floor hardener is a water-based, non-toxic, harmless, non-flammable liquid penetrant. It can effectively penetrate into the ground 3-8mm, and chemically react with the inside of the cement, so that the cement floor becomes a dense whole.

Fourth, universal repair mortar.

Universal repair mortar has good fluidity and can be constructed without construction experience. All you need to do is clean the ground and spread the mortar directly on the damaged ground.

Most of the sand on the cement floor is caused by the light cement ratio, poor sand quality, and improper maintenance in the later stage. Having said so many ways to fix it, prevention is the most important thing.

Dust, sand, and cracking of the cement floor? In this way, the dust and sand and cracking of the ground can be solved, which are the problems that can easily occur during the use of cement floor. After the cement floor is made, generally after half a month, the cement floor will begin to slowly appear dust and sand, cracking and other problems, and most people are taking some methods such as waxing to solve or not solve directly, but this can only slow down the speed of ground damage, and can not prevent the occurrence of dust and sand on the ground, which is a method of treating the symptoms but not the root cause.

Seeing this, many people may ask, is there any way to prevent dust and sand and cracking on the ground? The reason why the cement floor is easy to dust and sand and crack is because its own structure is loose, and the ground pressure will destroy the cement floor structure, resulting in dust and sand and cracking on the ground. At present, the cement floor hardener on the market can solve the problem of loose cement floor structure, and the cement floor hardener can penetrate deeply into the ground for 3-8mm, react with the cement floor, and generate a network structure to fill the pores of the cement floor, making it a dense whole, and greatly improving the strength, hardness, wear resistance, permeability and other properties of the ground.

After the cement floor construction cement floor hardener, the sealing of the ground is improved, and there is no need to worry that the dust will be precipitated from the pores of the ground, and the problem of dust and sand on the ground can be easily solved, and oil and other substances will not penetrate into the ground to form stains, as long as it is treated in time, it can leave no traces, keep it clean for a long time, and reduce the cleaning cost of the ground. After the construction of cement floor hardener, the service life of the ground can reach more than 30 years, and one construction saves 30 years.
