What to do if the ground is peeled and turned into sand The solution to the aging and powdering of t

Oujin floor penetrant has excellent adhesion, strong penetration of liquid materials, fast drying, strong wear resistance after effective penetration, and has good chemical resistance and water resistance, the product through effective penetration, and concrete and stone components to interact, so that the reaction layer solidified into a solid entity, and blocked the capillary pores of concrete, to obtain a dust-free and dense whole, thereby improving the original concrete wear resistance, compression resistance, compactness and impermeability. It can meet a variety of different use needs and environmental differences, and is suitable for ash treatment of cement floors such as factories, warehouses, docks, underground parking lots, etc., and the color of oil-based cement penetrant can be adjusted (generally colorless, medium gray, green, blue, red, yellow with lines, etc.).

The reasons for the non-wear-resistant sand of cement concrete floor include insufficient cement strength, excessive cement leakage, excessive cement mud content, insufficient cement dosing, improper maintenance, cracking and pulverization, cement concrete aging, and cement tamping caused by loose sanding and ash dust on the ground. Seiko floor sand treatment agent is a colorless, odorless, highly permeable water-soluble product. It is specially developed for the sand and dust generated by the existing concrete floor that is not wear-resistant and has low strength.

The Seiko ground sanding treatment agent is sprayed on the surface of the concrete, penetrates into the concrete to activate the cement hydration reaction, and the active ingredients can quickly react with the free calcium in the concrete, generate crystalline colloids to fill the structural voids, increase the compactness of the structure, and make the concrete surface form a hard strong Mo, and then improve the watertightness, strength and wear resistance of the concrete 0 2 Improve the compressive and abrasion resistance of concrete, so as to achieve permanent sealing, no dust, firm, wear-resistant, sand-resistant, Resistant to water and most industrial chemicals, it is the ideal industrial floor with a stylish and beautiful appearance.

The pavement of many streets and alleys is cement pavement, and after the cement floor is used for a period of time, it is easy to have problems such as peeling, so how to deal with the peeling of the cement floor? Next, I will briefly introduce it to you.

1. The cement floor is peeled, we need to shovel all the places where the ground is peeled, and clean the ground, and try to make the ground free of floating dust and debris. Next, we apply the sealing curing agent material, and use brushes and other tools to evenly coat it on the ground; In the next step, we repair the ground, the surface of the base should be free of hollowing, cracks, floating dust and other phenomena, we will mix the polymer crystal repair material, evenly brush the place to be repaired, and then we use the repair agent to mix the cement mortar for repair, after repairing the ground, the surface is compacted and smoothed.

2. According to the experts of Qeeka Home, cement floor peeling is a relatively common cement pavement disease, which may be caused by construction, natural climate and other reasons. For example, the ratio of cement and sand is out of balance; The cement layer is too thin, and the original ground has not been specially treated; Cement destruction is not properly maintained, and so on.

3. When we carry out the construction of the cement floor, we should first clean up the base layer, if there is oil stain on the surface of the base layer, you can use the diluted caustic soda to clean it, and then rinse it with clean water. The base should be clean and smooth, without hollowing, cracks and other problems. After the base is cleaned, the cement mortar can not be painted immediately, and we need to water the wet ground the day before construction, so as not to have insufficient adhesion between the base and the cement.

4. We should also pay attention to the ratio of cement sand, which should be controlled between 1:4 and 1:5; The cement floor for home decoration is usually made of fine sand, and its proportion can be appropriately adjusted.

Only when the proportion of cement and sand is appropriately blended, it is not easy to have problems such as anti-sand and cracking. We measure the height difference at the beginning of the cement floor, and if there is a height difference on the cement floor, it is necessary to carry out the smoothing work before the cement solidifies.

Summary: Regarding what to do about the peeling of the cement floor, the fiber will be briefly introduced to you here. I hope that after reading this article, I can provide you with reference and help when dealing with cement floor peeling. After the cement floor is paved, it must be sprinkled with water and the maintenance workers are sold.

Enter the area and get the decoration for free**].

1.Clean the floor: First of all, you should clean the ground and remove the dust, oil, stains, etc. on the ground, which can be cleaned with detergent or high-pressure water gun.

2.Repair the floor: knock off the peeled part of the ground with a hammer, then repair it with cement mortar, fill the mortar to the ground, and smooth it with a trowel.

3.Waterproofing: After the ground is repaired, a layer of waterproofing can be applied to prevent moisture from seeping into the ground and causing the ground to peel again.

4.Strengthen maintenance: After repairing the nuclear stupidity, it is necessary to strengthen the maintenance, keep the ground dry, avoid erosion by moisture, and also avoid heavy objects crushing or trampling, so as not to affect the repair effect.

Cement pavement peeling is a relatively common cement pavement disease problem, as for the cement pavement peeling reasons are many, that is, there are construction reasons, but also in the climate and natural reasons, as well as some man-made reasons, etc., cement pavement peeling generally belongs to the cement pavement surface disease, peeling off the place all shoveled off, first solidified and then repaired, after the ground is cleaned up, the sealing curing agent material is painted, the flatness of the ground will not change after the material is painted, and then the cement sand is mixed with the repair agent for repairIt is very hard and wear-resistant after drying, and it is not easy to fall off, and it can often be rolled back and forth by vehicles.

You can also ask someone to repair the peeling pavement in time through professional cement pavement repair material and concrete pavement repair material, and compared with some deep cement pavement diseases, cement pavement peeling generally only needs to carry out a thin layer of cement pavement repair material repair material repair material on the peeling part to repair the peeling part.

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 quick repair with universal repair mortar, 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.

If the surface of the outdoor cement floor is sandy and peeling, then the loose sand on the surface should be knocked up, cleaned and then re-applied to the cement surface.

Spray wet with water, then fill mortar, sprinkle some dry powder or polish after solidification, and sprinkle dry powder to save some trouble.

This condition is considered aging. It should be refurbished and disposed of.

The reason is that the cement floor is not strong enough. There are the following reasons for the sand and shelling of the cement floor: 1. The strength of the cement mortar is too low (that is, the label is too low) and it is easy to be damaged.

2. The water-cement ratio of cement slurry is too large, which reduces the strength of cement stone and is easy to be damaged. 3. The maintenance is not done well, and the existence of water is a necessary condition for the hydration reaction of cement. When the ambient humidity is very dry, the moisture in the cement will evaporate quickly, so that the cement will not be sufficiently hydrated and the hardening will stop.

Treatment: Use an appropriate water-cement ratio and cement mortar to meet the strength required by the design, and do a good job of maintenance after construction.

Find out the cause of sanding, whether it is the cause of the construction party or the reason of the mixing plant, and avoid it next time.

1) Polishing off the surface layer, watering and curing, if also sand with the treatment agent on the market. Such as oily permeable cement floor sanding treatment agent, epoxy resin mortar, etc.; Certain cementitious polymer repair mortars.
