How to solve the problem of ash and sand on the concrete floor?

Ground flouring refers to the feeling that the ground is powdered by concrete for some reason, and no matter how much it is cleaned, it cannot be cleaned, and then the phenomenon of peeling and powdering appears. In severe cases, stones will appear, which will bring great inconvenience to work and life. Therefore, timely treatment of the sand on the ground will improve the service life of the ground and reduce costs.

Sand on the ground should be a situation that most people don't encounter. Because most of the sand on the ground happens on the concrete floor, and now the cement floor in people's homes is only the better ground for our kind of floor. Normally, we will lay a second layer of floor tiles on the concrete floor.

However, it is common to see sand on the ground. Probably many people don't know what kind of situation the sand on the ground is, and they don't know what we should do when we encounter sand on the ground.

Ground sanding refers to the fact that freshly poured concrete or used concrete begins to ash for some reason, and there is a feeling that it cannot be cleaned. Then it will peel, sand, and in severe cases, even pebbles. If it deteriorates further, it will fall to pieces.

After heavy pressure, cracks and potholes appear in the ground. If this phenomenon only appears on the ground or some similar situations have not yet appeared, treating it with a concrete floor sanding agent will greatly improve the quality of the concrete.

Concrete hardener is specially developed to solve the problems of ash, sand, lack of strength on concrete floors and walls. It is a new type of water-based composite material with a unique formula, which can penetrate into the surface layer of concrete 3-10mm, and undergo a series of complex chemical reactions with free substances in the concrete to form a dense whole with a three-dimensional network, thereby greatly improving the surface strength of the concrete, and achieving the effect of hardening the base layer and preventing and controlling sand. Its service life is the same as that of concrete, and it is easy to apply.

It only needs to be painted on the surface of the concrete. The VOC and free formaldehyde of the product (according to GB18583-2008 standard) fully comply with the industry standard, and are far lower than the standard value, which is a safe and environmentally friendly product.

If you want to effectively solve the problem of sand taking off from the concrete floor, you should properly carry out sprinkling maintenance, and use some Portland cement with guaranteed quality.

First of all, the place where the ash and sand need to be pulled up, wet with water, and then blended in a ratio of 1:1 for leveling.

The sprinkling maintenance is not in place, and it is necessary to sprinkle water frequently, and maintain it frequently, or it is caused by the fact that the cement is not up to standard.

Special attention should be paid to many details in the decoration, especially the ground construction. Some owners who use cement floors directly are prone to sand and ash after using them for a long time. With the extension of service life and the effects of carbonization, water erosion and weathering, the floor surface will continue to be powdery, affecting normal use.

When the cement surface is rough and dry, touching the cement surface with your hands will not fall off.

When walking around, there will be loose sand grains or flakes of peeling cement crust, which is ground sanding. Some have hollow drums and small depressions when they hit the ground, which will crack under the action of gravity, seriously damaging the use function of the ground. The strength grade of the pavement or concrete floor of the industrial plant shall not be less than C20.

It should be used when determining the mix ratio of 5. The content of cement and fly ash shall not exceed 20%, and fly ash cement shall not be used. When pouring concrete floor slabs with ready-mixed concrete, the construction slump shall not be greater than 150mm.

When the ground layer is constructed with fly ash cement, the cement mortar direct plastering method shall not be used, and the dry and hard mortar shall be used for leveling, and then the surface shall be plastered and rolled with cement slurry. Since this method does not have a slurry extraction process, there will be no fly ash floating and no sand will be sprinkled on the concrete surface. There is a simple and economical solution for sanding existing concrete surfaces:

Hardening is performed with a concrete sealing curing agent, which is a lithium-based chemical hardener. It works entirely through penetrations and does not alter the appearance of the original concrete surface. Its main function is to improve the hardness and wear resistance of the surface of the frosted concrete, and the effect after treatment is permanent.

The ash and sand in the concrete may be due to watering and curing problems, resulting in a lack of water in some parts of the ground, which affects the hydration reaction process of the cement. Therefore, the ground should be maintained regularly. The maintenance time should be more than 7 days or so.

It is best to sprinkle water every day. Do not use quick-drying, let it dry naturally. It could also be that the cement itself is not up to standard and does not hydrate and cure well.

The mud content of sand is too large, which affects the cement hydration process.

Answer: concrete ground ash, sand may be related to the quality of the mixture and cement when the ground was made, the ground sanding, can be cured, curing is to first grind the ground with a polishing machine, and then sweep the ash produced after grinding, and then splash a special curing agent, from now on will not be ashed, both bright and firm.

It can be repaired, it is best to choose the right material for repair, Portland cement can be used, so that the problem can be solved very well, and you need to find a professional person to deal with it.

Choosing a better material, sprinkling water frequently, having a good grasp of the calendering time, and maintaining it in time after the completion of the project can effectively deal with related problems.

Compared with slag cement and pozzola cement, ordinary Portland cement has the characteristics of good water retention, small dry shrinkage and high early strength.

I think the best thing to do is to sweep the floor clean and re-layer the concrete.

I think this situation can be smeared again with cement mortar, so that the dust can be stopped.

In recent years, the retro industrial style has been established in the form of scattered bends, and there are many houses, offices and shops with industrial-style décor. One of the most important aspects of industrial decoration is soil treatment.

What is the reason for the dust and sand on the ground?

1.Excessive water than ash: Mixed concrete will contain a lot of water, causing the surface of the concrete to seep out, which then reduces the surface strength of the concrete.

2.The classification of sand and gravel is unreasonable and the sludge content is high: the classification of unreasonable aggregates and sand that is too fine and sanded also causes the soil, affecting the early cement hydration and concrete coagulation.

3.Excessive vibration permeability during construction: The seepage on the concrete surface becomes faster, resulting in low resistance on the concrete surface.

4. Improper maintenance, failure to maintain in time or improper maintenance, exhibition or strong wind caused by huge loss of water on the concrete surface, the surface is not completely hydrated, resulting in less resistance.

5. Other original balance factors: the calendering is not well mastered, the concrete surface does not reach a certain strength of people's work, and the building on the concrete surface freezes at low temperature.

How to deal with dust and sand on the ground?

1.Ground Dust and SandIf the grinding area of the cement floor is small and the floating sand is small, pure cement can be used to cover the surface. Cement can be made from regular Portland cement.

2.If the ground is large in the area of cement floors, but the circumstances are not very serious, it is recommended to use a treatment agent for the professional land that is in its structure and its effect is obviously simple and boring.

3.If the ground is dusted and sand and is very severe, it is advisable to repair it, remove the original surface layer and replace it. Replacing the surface layer is equivalent to rebuilding.

Precautions during construction are also precautions for sanding on concrete floors. This is very important, so it will be listed separately.

The above content is the cause and solution of ground ash and sand, thank you**, during the whole construction period, the room temperature should be strictly controlled, so as not to have an adverse impact on the construction effect. Therefore, it is not recommended for everyone to work in winter. Because, when the room temperature is lower than 10, the glue is very easy to freeze and cannot be proportioned.

In order for the glue to melt in its natural state, temperature control is crucial.

If the cement floor is sanded and dusted, then the concrete reinforcing agent can be brushed first, but this method is usually only suitable for those cement floors with a light degree of ash and sand, and the other is that it should be painted several times when painting.

Another method is to polish the cement floor first, and then apply the concrete and wall agent after polishing, and then polish it, which is also very useful.

If the sand on the ground is more serious, then you can pry off all the sand places, and then re-pour the concrete ground closed branches, and then go to the floor, it is recommended to hire special workers to actually operate.

What is the cement floor that looks good and is cheap? There are many materials that can be laid on the cement floor, such as cement floor paint, which is used to decorate the cement floor, which is simple and convenient, and has a variety of colors, and can be selected according to the overall decoration style of the house.

In addition, floor tiles are suitable for bathrooms, kitchens and large areas of cement floors, it has the characteristics of non-slip and durable, in addition, you can also choose composite laminate flooring, about 40 60 yuan per square meter, it looks very high-end to use, and it is not very expensive, the disadvantage is that it is not suitable for frequent flooding and more humid cement floors.

When will the renovation floor protection be removed? Decoration ground protection, need to be removed after the completion of the carpentry project, carpentry door cover installation, kitchen ceiling, bathroom ceiling, lamp installation, etc. can be removed. The dismantling is relatively simple, you can directly tear off the protective film on the ground, and you must hold the strength and speed.

If you are using tile wax, you also need to buy a tile wax cleaner to wipe it. When choosing a ground protective film, it should be noted that the pearl cotton material is the most cost-effective, and it is also relatively cheap, as long as you don't buy the moisture-proof film material, it is more likely to be damaged.
