How to solve the problem of sand on the wall? What are the reasons?

In recent years, the retro industrial style has been established, and many industrial styles such as houses, offices and shops have appeared. The most important point of industrial style decoration is the treatment of wall surface, which is a simple and direct cement wall. So, what problems will cement walls face? The polishing of cement wall is the most important problem, which can be considered as the quality problem of engineering construction. Today, let's briefly introduce how to solve the problem of wall sand, and what are the reasons.

What is the reason for the sand on the wall 1? Excessive water-cement ratio: the water content of mixed concrete is relatively large, which leads to water seepage on the concrete surface and reduces the surface strength of concrete.

2. Unreasonable gravel gradation and high silt content: unreasonable aggregate and too thin soil sand will also cause wall polishing, which will affect the premature hydration and condensation of cement slurry.

3. Excessive vibration during construction: the concrete surface intensifies water seepage, which greatly affects the external resistance of concrete.

4. Inappropriate maintenance: failure or improper maintenance in time, exposure to the sun or strong wind caused a large amount of water loss on the concrete surface, and the surface was not fully hydrated, resulting in decreased resistance.

5. What is the reason for the sand on the wall? The rolling time is not fully mastered, the surface of the artificial concrete does not reach a certain force, and the low-temperature structure on the surface of the concrete freezes.

How to solve the problem of wall sand 1? How to solve the problem of sand on the wall If the polished area of the cement wall is small and there is little floating sand, it is best to cover the surface with pure cement suspended material. Cement can be made of ordinary portland cement or portland cement.

2. If the polished area of cement wall is large, but the circumstances are not serious, it is recommended to use professional wall treatment agent, which has simple structure and obvious effect.

3. If the concrete wall is polished in a large area, which is very serious, how to solve the problem of sand on the wall? It is suggested to repair, remove the original surface layer and replace it. Replacing the surface layer is equivalent to reconstruction. Precautions during construction are also used to polish cement walls. This is very important, so Bian Xiao will be listed separately.

Because this is a common phenomenon, there is no need to worry about ChuXiang problem. How to solve the problems and causes of wall sanding summarized in the above small series, I hope to help everyone.
