3.The construction is simple, only need to dilute the material with water proportionally and spray the road surface.

At present, most of the pavement sand repair is repaired with Guheng cement pavement sand treatment agent.

Cement pavement sand shows that the cement pavement is likely to have the problem of tofu slag engineering, the cement floor created by the professional construction team will be built with good compatibility and high strength. What kind of cement strength is more appropriate?

First, the repair method of cement pavement sanding.

1. First of all, we need to use a large grinding machine to polish the ground, polish and clean the original cement pavement, and repair the cement pavement surface with the help of better compatibility cement is the best solution.

2. However, this repair method can only solve the urgent need, if the cement floor is not renovated as a whole, then there will still be such a phenomenon in the future, so the choice to redo the road will be more effective to avoid the problem of sand on the cement road in the future.

3. When repairing the cement pavement, it is also necessary to use the cement that matches the color of the raw materials, and if the color of the cement is too different, it will also directly affect the appearance of the cement pavement.

2. Which specification of cement has greater strength.

There are many cement specifications on the market, among many specifications, it is very common to choose 325 cement to do the road, the compressive capacity of cement of this specification is very strong, and it is not easy to have the problem of sanding.

3. Advantages and disadvantages of cement roads.

1. The obvious advantage of cement road is that its cost is relatively low, compared with asphalt road and asphalt pavement, the overall cost of cement road is very low, and the implementation of the construction plan of cement road will be relatively simple.

2. However, compared with the other two kinds of pavement, the service life of the cement road is relatively short, and the driving on the cement pavement and the asphalt pavement is completely different.

There are many ways to repair cement pavement sanding, and here are some common repair methods:

1.Filling method: Use cement pavement filler to fill the sanded area and make it smooth. This marking method is suitable for sand raising in a small area.

2.Thin layer repair method: use the thin layer of cement pavement repair material to lay a thin layer on the sanding area to restore the leveling. This method is suitable for sand raising over a large area.

3.Integral repair method: The entire pavement is repaired by using cement pavement integral repair agent. This method is suitable for sanding the entire road surface.

4.Replacement and repair method: replace the sanded pavement slabs and use new cement pavement slabs for paving. This method is suitable for severe sand situations.

5.Cement repair material regex tremor: This is a kind of repair material specially used to solve the damage of the surface layer of cement road.

This method is suitable for the use of eight major pavement diseases: sanding, peeling, exposed stone, freeze-thaw, hemp surface, network cracking, and potholes. Domestic brands such as Lu Lao Tie Ju Defeat, Jiuda Kang, etc. are very good, new mixed materials, you can use it directly with water.

It should be noted that different repair methods are suitable for different sand situations, and the appropriate repair method can be selected according to the actual situation. At the same time, when repairing the cement pavement, it is necessary to pay attention to safety and quality issues to avoid affecting traffic and pedestrian safety. "

Cement pavement sanding repair method:

1. A small part of the area is sanded.

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

2. Half of the area is sanded.

If a ground is close to the general area of sand, this kind of plastering mortar will not work, then it is necessary to use professional repair materials to treat, repair mortar and water mixing, smeared on the ground, after 3 hours of drying, you can walk around.

3. Most of the area is sanded.

Most of the area of sanding, the use of ordinary repair mortar will not work, must use universal repair mortar, specific large area of ground sanding, suitable for the use of universal repair mortar for rapid repair, the method is as follows:

1) Pour the interface agent on the ground that needs to be repaired, and do a good job of base treatment.

2) Then pour the all-purpose repair mortar and throw it flat with a special tool.

3) In order to make the ground shiny, more beautiful and more durable, it is recommended to do fixed-line treatment to make the ground as bright as new.

The sand area is small, use cement mortar to directly wipe the sand place, or use a professional ground treatment agent, mix it evenly with water, spray it on the sand place, and continue to water and moisten it in the later stage, and then wipe the surrounding area clean. The area is large, the ground is sprayed with interface agent first, and then directly applied to the ground with repair mortar, and it also needs to be calendered, and if conditions permit, the ground is cured and polished.

In fact, there are not only man-made but also other reasons, such as the cement ratio is light, if it is not well blended, it will also be affected, simply speaking, the proportion of water and sand in the decoration process is too much, and the cement material is too little, so that the vertical cement mortar water seepage situation is formed, so as to reduce the strength on the surface of the cement floor will lead to the cause of cement floor sanding.

The reason for the abrasive belt on the cement pavement

1. The quality of the purchased sand Yu Lingzi is unqualified, and there will be certain quality problems with all the use of cement and lime, if the use of unqualified cement or lime that is not up to standard is likely to form sand on the ground, so we must go to the regular manufacturers to buy these materials when we buy them, so as to ensure the quality of the orange to be qualified.

2. There is another reason that the maintenance is not done well during the reconstruction, which will lead to the later ground maintenance or insufficient maintenance, and the concrete surface layer on the ground will be caused by sun exposure or wind blowing to have a large amount of moisture disappearing, resulting in the failure of the ground surface layer to obtain the corresponding water absorption and maintenance, and directly reduce the strength of the ground surface, so the cement floor maintenance is very important.

It is one of the indispensable materials in construction, and it is usually used with steel bars to increase the strength of the building. Concrete has a good performance in road engineering, basically the road is poured with concrete, and the pressure bearing capacity is extremely strong. However, in the use of concrete pavement, there is a more common problem, that is, sanding, so how to repair the concrete pavement sanding?

Let's take a look with Qeeka Home experts. 1. How to repair the sand of the concrete pavement needs to determine the sand range first, and mark the sand parts with the marking method, so as to facilitate the calculation of the amount of materials used for repair, and at the same time can also remind the people who come and go; Then remove the dust and impurities within the identification range and rinse with a high-pressure water gun; After there is no open water on the surface, the stirred pavement repair material is paved on it, and it can be cured for a period of time after scraping. Second, what to pay attention to in concrete pavement construction 1, pay attention to mixing concrete mixing is noteworthy, first of all, the water distribution in the allocation should be strictly controlled and burned, if you do not pay attention, it is very likely to appear the risk of collapse.

For cement gradation, aggregates, etc., can not be sloppy, to maintain stability. The temperature of the cement is also very critical, the cement starts to mix before it cools, which will lead to a high temperature of the concrete, which will affect the problem of water absorption. 2. Pay attention to the need to sprinkle water on the road surface before paving, and the amount of water is not fixed, it should be determined according to the base material, temperature, humidity, wind speed, etc., and the sprinkling should be uniform, and there can be no water storage.

If the amount of sprinkling water is insufficient, the base layer will be drier, and the bottom of the concrete will be prone to small cracks after construction. Summary: The above is about how to repair the concrete pavement sanding, and what to pay attention to in the construction of concrete pavement, I hope the content shared can give you some reference, if you want to know more about relevant knowledge, you can **** Qi family network information.

The repair method of cement pavement sand and peeling is as follows:

Tools: high-pressure water guns, brooms, vertical mixers, etc.

Raw materials: cement, water, etc.

Specific steps: 1. First of all, clean up the damaged cement pavement base, and dispose of the loose stones and sand.

2. Wash the road surface with a high-pressure water gun to prevent sewage from backflowing, and try to flush in one direction.

3. Rinse it clean, and blow the open water on the surface layer with a road hair dryer to keep the road surface wet and free of open water.

4. Fully stir the prepared materials, and use a vertical stirring rod to stir until there is no dry powder and no bubbles. Usually, stirring for 3-5 minutes.

5. The quick-repair material with uniform stirring should be constructed as soon as possible within 20 minutes. During the construction process, it is necessary to ensure that the repair surface is consistent with the height of the original ground, so as not to cause unevenness of the road surface if it is too high or too low.

6. The repaired cement pavement should be maintained in time, and it can be maintained once within 24 hours.
