What should I do if the emery floor is damaged?

What do you need to pay attention to in the construction process of corundum wear-resistant flooring?

Emery wear-resistant floor is a ground form in which a layer of ground hardener material is evenly spread on the surface of the concrete during the initial setting of cast-in-place concrete, and it is repeatedly wiped and formed by a mechanical trowel.

Baohe flooring. Emery wear-resistant floor is constructed together with concrete, and the construction period is short, so it needs to be extra rigorous in the construction process, let's take a look at some matters that need to be paid attention to in the construction process of corundum wear-resistant floor.

1. The strength of the base concrete needs to be higher than C25, and the thickness of the base concrete layer should not be less than 80, and the elevation of the formwork needs to be strictly controlled. During winter construction, the temperature should be higher than 5, and when the temperature is low, the early strength agent should be appropriately added to the concrete.

2. It is necessary to correctly grasp the spreading time of ground hardener according to factors such as temperature and concrete mix ratio. Spreading too early can reduce the effectiveness of the abrasion-resistant material by allowing the wear-resistant material to sink into the concrete. If spread too late, the concrete will already solidify and lose its cohesion, making it impossible for the wear-resistant material to bond with it and cause it to peel off.

Therefore, in order to spread the ground hardener correctly, the correct spreading time needs to be controlled by experienced construction personnel. It is necessary to pay attention to the relationship between the coagulation performance of concrete and the spreading time in the continuous spreading construction, and continue to accumulate experience.

3. The spreading should be uniform in thickness, clear in direction, no omission, no accumulation, and proper spreading at the corners.

4. After the polishing process is completed, the hardener wear-resistant floor should have an obvious mirror effect, uniform color, and no obvious traces when wearing soft-soled shoes. In general, the surface layer of the hardener wear-resistant floor can reach C80-C100 concrete strength.

Emery wear-resistant floor has the advantages of high surface hardness, high density, wear-resistant, and dust-free. Therefore, in order to ensure the performance advantages of corundum wear-resistant flooring, it is necessary to be rigorous and meticulous in the construction process. In this way, the quality and life of the corundum wear-resistant floor can be guaranteed.

Emery floor belongs to the cement-based floor, if it is damaged, it is not recommended to repair it with cement-based materials, there will be obvious traces, and it will be separated after a long time.

It is advisable to repair with an elastic material, such as epoxy floor paint.

Or after repairing with cement-based materials, lay other materials as a whole, such as bricks, floors, etc.

The main reasons for the cracks that may occur when pouring the base concrete are: the strength grade of the base concrete is high, and the heat of hydration generated is high; Winter construction, the ambient temperature is low, and the temperature difference between the concrete and the ambient air temperature is large; Improper maintenance, when the concrete temperature is high, cold water is poured for curing, which will also produce irregular multiple micro-cracks, and severe cracks can lead to leakage of the bottom plate.

In order to prevent cracks, it is necessary to set up expansion and post-pouring belts from the design, cut joints after the completion of the emery ground, improve the construction process during construction, reduce the temperature stress of the concrete and improve the anti-performance of the concrete itself.

In order to prevent cracks in the concrete at the shady corner, in addition to using the concave and convex plane formation as little as possible from the design aspect, and using structural measures such as additional steel bars at the shady corner, the concrete construction quality of the shady corner should also be ensured in the construction, and the curing agent should be covered in time, drenched with water, or sprayed with curing agent for curing, and the control of the demoulding time should not be too early.

There are many reasons for cracks, the distance between expansion joints is unreasonable, the ground ash is not enough, the ground foundation is shallow, the relationship between geothermal heat, there is no way to completely recover in this situation, if the place is very important, use marble glue and gray cement, the color is adjusted to the same as the ground for repair, grinding and leveling, if it is a general place, it is poured with plain gray cement to level it.

There are many reasons for cracks, natural reasons, heavy objects back and forth rolling may cause cracks to be observed for a period of time, whether the cracks continue to expand, and then repaired after stability 1, micro cracks can be repaired with cement repair paste, directly scraped at the place to be repaired after stirring evenly, there will be color difference after repair, very hard, waterproof, strong compressive ability, not easy to fall off.

2. Wider and deeper cracks can be repaired with a repair agent mixed with cement sand, which is more thoroughly filled by slotting, and is very hard after repair, and is not easy to fall off.

Depending on the crack situation, different treatment methods are selected.

Cement Remediation Specialist.

Emery wear-resistant floor crack treatment method:

1.Ground cutting and cracking treatment: due to the construction of a large area of corundum wear-resistant floor, resulting in unevenness and unevenness of the ground after construction, the flatness is not the same, which causes the problem of cracks, therefore, when we construct a large area of corundum wear-resistant floor, we should cut the joints to prevent the growth of cracks and avoid repeated cracking of the corundum wear-resistant floor.

2.Clean up the base layer: through the corresponding tools and means, clean the base layer of the cracked part, and remove the dust and sundries of the cracked part without damaging the bottom plate, so as to provide convenience for the follow-up construction.

3.Grouting compaction: Combined with the actual situation of the crack, select the appropriate grouting point, use the impact hammer to make the grouting hole, and clean the dust. An air pump should be used to press water into the cracked part of the concrete and wet it to improve its bonding with the slurry;

Then, the water is mixed with the corresponding glue and injected into the crack. Then, using a hand mixer, the cement is configured to evenly press the cement slurry into the cracks until the cracks are overflowing.

Kiss, emery ground crack treatment method: 1Surface treatment should be carried out for cracks on the surface that require anti-seepage, impact resistance and wear-resistance.

2. To weaken the integrity, strength, impermeability of the structure and the cracks that cause the corrosion of the steel bar, the grouting treatment should be carried out. 3.For cracks that endanger the safe operation of the building, in addition to grouting treatment, other reinforcement measures should be taken if necessary.

4.Cracks that are sensitive to temperature should be treated after the low temperature season or when the crack opening is large in the cherry blossom stage.

5.Active cracks must be treated with flexible shirt bush material.

Summary. After the emery floor is used for a long time, there will be sand and cracking, and the old emery floor can be cured and renovated. The curing and renovation of the emery floor is to use the concrete sealing curing agent material to polish and polish the ground, so as to make the ground super wear-resistant, and can withstand the long-term rolling of trailers and forklifts without dust and sand.

1. Use a grinding machine to remove the residual oil marks on the surface of the rough corundum floor, and repair the damaged parts with the floor repair agent, and then clean the ground.

2. Dilute the concrete sealing curing agent with 4-5 times of water, and evenly roll it on the dry ground with a roller (the amount per square meter is about 4 hours, and it will be fully penetrated for 4 hours.

3. When the surface of the emery floor becomes viscous, clean the ground thoroughly with clean water, absorb the sewage, and dry the ground.

4. Use concrete resin sheet 400 or soft grinding disc (500) to grind the floor in turn.

5. Polishing the ground, concrete polishing disc 800 or soft grinding disc (2000) polishing the floor, and the construction can be ended by pushing the dust to clean the dust.

Abstract: The service life of corundum wear-resistant floor is inseparable from the later cleaning and maintenance, do you know how to clean the emery floor and how to make the emery floor bright? First of all, the emery used in the emery floor is a very strong material, which can be cleaned directly with a cleaning agent.

Secondly, the construction of concrete sealing curing agent on the emery floor can make it brighter, is it very simple? Come with me to the article and take a look! 1. How to clean the emery floor.

Emery wear-resistant floor has the characteristics of high strength, wear resistance and impact resistance, with a smooth and smooth surface, and can be configured with various colors to meet the aesthetic requirements. It greatly improves the density of concrete, reduces dust, increases the oil resistance of the ground, and forms a high-density, easy-to-clean, and impermeable ground. It can be constructed together with the concrete floor, the construction period is short, and it is widely used in warehouses and other places.

In daily maintenance, the emery floor should also pay attention to a certain amount of cleaning and maintenance, so do you know how to clean the emery floor?

The emery floor can be cleaned directly with detergent, and emery is a very strong material that is not afraid of washing.

Second, how can the emery floor be bright.

The key process of emery floor gloss is polishing, and the ground will be shiny if the polishing work is done well.

Most people who do emery floor construction may have encountered such a problem: the small area of the test block is easy to polish, and the ground luster is very good, while the large area of the emery floor is more difficult to polish, and the floor degree is not as good as the previous small test block.

For the problem that the light sensitivity of the emery floor is not high, we tried to spray the method of curing agent, but then there was a whitish problem, and after drying, it became a thin film, and the effect was not ideal.

In fact, you only need to apply the concrete sealing curing agent on the emery floor, and the problem is solved.
