How to repair the cement concrete floor with frequent ash?

What to do if the cement floor is dusted.

There are two main reasons for the ash of cement floors, one is improper maintenance, but improper production.

1. Excessive water is added to cement during production, which will cause the water-cement ratio to be too large, causing ash on the cement floor; If it is more serious, it will cause sand on the cement floor.

2. When we make cement floor, we need many matte concrete surfaces, if we don't do this, it will cause the cement floor to be not strong enough and easy to ash.

3. There is also the low quality of the cement used.

How to deal with the ash on the cement floor.

1. The concrete sealing curing agent is sprayed on the ground at low pressure, and then the material is evenly distributed with a microfiber mop or soft hair broom.

2. The ground will be kept in a wetted state of 15-20, and then sprayed on the porous ground and the ground that has shown the area of absorbing dry material.

3. When the material is hardened, do not use a microfiber mop or soft hair broom.

4. It is to pave a layer of cement-based materials, such as self-leveling cement, fine stone concrete, etc., without affecting the elevation of roads and buildings. This is actually a remedy, and serious problems may require removing the original concrete and re-pouring the concrete.

5. It is made up by using a thin layer of material. For example, the construction of a layer of 2 3 mm self-leveling cement is repaired with polymer-modified putty scraping, epoxy and other resin materials.

The quality of your ground is not up to par, so it is often dusted, and you can re-mark a layer of cement, and it will definitely not be dusted.

If the cement concrete floor is often ashed, it may be that the quality of the ground is not good, in this case, you can use the hardener to repair, the repaired ground will be greatly improved in terms of hardness, wear resistance, etc., such as the brand of Bondimei hardener is very good in this regard.

When building a cement floor, it is necessary to do a good job in all aspects of the process to avoid ash. What are the reasons for the ash of cement concrete floors? PChouse will take you to find out.

1. Cement quality problems: cement is counterfeit, or expired and wet.

2. The amount of cement is too small: the construction liquid letter file cuts corners in order to save costs.

3. The size of the water-cement ratio in chaos: If the water-cement ratio is too large, the concrete will leak water.

4. Construction technology: process errors, improper processes, and problems during maintenance.

These factors will affect the strength of the cement concrete floor, the strength is insufficient, and the aging will be accelerated under the action of external forces (such as friction, forklifts back and forth, carrying heavy objects, etc.), and the ground is easily damaged.

5. Ground aging and weathering: The service life of concrete is short, and the cement concrete floor is easily damaged due to its own internal reasons after entering the aging period.
