How to deal with the sand and ash on the cement floor?

1. Coat concrete reinforcing agent.

This method is more suitable for the cement floor with a relatively light degree of sanding, and the problem of sand and ash on the cement floor can be solved by brushing on the cement floor with concrete reinforcing agent.

2. Brush with a special ground sanding treatment agent.

This method is more suitable for sand raising on the old cement floor, which can be solved by applying a special sand treatment agent on it.

3. Re-pour the concrete floor.

If the sand on the cement floor is more serious, the concrete floor must be re-poured and then treated with the floor to solve the problem of sand on the cement floor.

First, the cement floor sand and ash treatment method:

Cement floor sand and ash treatment with Nalut concrete sealant curing agent AC agent. NALUT AC agent is also known as cement floor sand and ash treatment agent. The sand and ash of the cement floor can be solved by the sand and ash treatment agent of the cement floor.

The following takes Nalut cement floor sand and ash treatment agent as an example to explain how to solve the problem of cement floor sand and extinguishing.

Principle of solution of cement floor sand and ash treatment agent: The main characteristics of Nalut cement floor sand and ash treatment agent are:

1.Abrasion resistance: Cement floor sanding treatment agent can solidify various components in concrete into a hard body, increasing hardness and compactness. After curing with cement floor sanding treatment agent, the wear resistance is increased by more than 6 times.

2.Hardening: After the cement floor sand treatment agent is treated, the Mohs hardness is 8, and the Mohs hardness is increased.

3.Impermeability: The cement floor sanding treatment agent can effectively penetrate into the concrete, and chemically react with it, lock the pores inside, play a permanent sealing effect on the concrete surface, and effectively inhibit water, oil and other surface dirt from entering the concrete.

4.Environmental protection: cement floor sanding treatment agent is a kind of concrete sealing, dust-proof, wear-resistant hardener, colorless, odorless, non-toxic, non-combustible, can make concrete firm and dust-proof; It can prevent moisture, oil penetration, alkalization, weathering, etc.

5.Dustproof: The cement floor sanding treatment agent reacts with the salt in the concrete to form a dust-free and dense whole on the surface of the concrete, which permanently avoids the precipitation of concrete dust from the surface voids.

How to deal with cement floor to reduce dust.

The cement floor of the factory is sand and ash, and I don't want to put in the high cost of treatment, I just want to treat it simply, dustproof and clean, and can withstand the environment of frequent driving.

The dust prevention of the factory floor can generally be made of epoxy flooring or concrete polishing flooring, but the cost of such products is high and the construction period is long, so it is not suitable for rapid processing scenarios.

<> oil-based one-component floor penetrant is a low-viscosity resin product, with high wetting permeability, rapid penetration and curing, forming a hard closed layer, eliminating dust, suitable for scenarios with high requirements for the workshop environment, and can withstand frequent forklifts and other equipment. There are water-based products, industrial-grade sand fixing treasure, why process industrial grade, because the general sand fixing treasure is used for home decoration, before laying the solid wood floor, a layer of interface agent painted on the cement floor, its strength can not reach the use environment of the workshop, and the sand fixing agent used in the special industrial ground is required, which can not only have a part of the chemical reaction with the concrete, but also can penetrate and close the ground of sand and ash, and the strength is higher. No matter what kind of product it is, it is recommended to test samples in advance and compare the results, because the material properties of different manufacturers are very different.

Concrete floors can be coated with concrete reinforcing agents, re-poured concrete floors, tiled or wooden floors, etc.

1. Coat concrete reinforcing agent.

This treatment method is only suitable for the new cement floor with a light degree of ash, buy concrete reinforcing agent in the market, and then paint 2-3 times on the cement floor. Regret Hong's demolition.

2. Re-pour the concrete floor

If the phenomenon of dust and sand on the cement floor is very serious, then it is best to re-pour the concrete floor and then make the floor. Emery flooring, concrete reinforcing agent flooring or epoxy jujube flooring can be, among which the concrete reinforcing material floor is low and more wear-resistant and durable than epoxy flooring.

3. Pave tiles or wooden floors

Regardless of the degree of sand and ash of the old and new cement floors, you can lay tiles or wooden floors on the cement floors. Cement floors can be chiseled or coated with grout, and tiled or wooden floors can be properly laid.

Causes of ash and sand on cement floors:

1. Raw material problems. In reality, many owners have suffered the loss of unqualified raw materials. The raw materials are mainly cement, river sand, and gravel, and if the cement strength grade used is too low or expired, it is damp and agglomerates.

It will definitely affect the strength and wear resistance of concrete. If the particle size of the sand and gravel used is too small or the mud content in the sand and gravel is too large, it will affect the bonding between cement and sand, resulting in reduced concrete consumption and absolute dust generation.

2. The water-cement ratio is too large, and some companies add too much water to the admixture in order to reduce costs, which will reduce the strength of the surface layer of the cement floor. After the completion of the cement floor, if the correct maintenance is not carried out for a period of 14-28 days, it is easy to cause the dehydration of cement mortar, which affects the strength and the quality problems such as peeling and dust and sand in the later stage.

There are three main steps to deal with ash and sand on the cement floor: 1. Remove the dust and various sand particles on the cement floor; 2. Pour the repair material on the ground; 3. Use a roller to paint the material evenly.

1. Remove the dust and various sand particles on the cement floor to ensure that the pure ground is in a flat state.

2. Then pour the repair material on the ground, making sure that every position is covered.

3. Finally, the material is evenly painted with a roller in the excitation booth, so that it can be repeated several times.

What are the causes of sand on cement floors?

1. The water-cement ratio is too large.

The amount of concrete mixed is too large, resulting in water seepage on the surface of the concrete, so the strength of the concrete surface is reduced, so after the construction is completed, the problem of sand on the ground will occur, which is mostly caused by the loss of lead during the construction of the project.

2. Improper ground maintenance.

This is also the key reason for the ground sanding, the maintenance measures in the early stage of construction are also very important, if the maintenance is not immediately maintained or the maintenance is insufficient, the surface is seriously dehydrated due to exposure or blowing, and the appearance can not obtain enough moisture, it will directly reduce the strength of the cement floor, resulting in the reduction of strength, so the problem of sand will occur when it is used.

3. Wrong choice of materials to use.

Because of the unqualified and too fine soil sand of various materials, the hydration of cement and the solidification of concrete in the early stage are caused, so the cement floor is sanded, which is very important in the selection of materials before the start of construction.

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.
