At present, the strengthening products and technologies of the marble surface basically rely on certain chemical materials to chemically bond with the stone, thereby improving the strength and hardness of the marble surface, and increasing the abrasiveness of the marble. To prevent and reduce the damage of the stone floor, it is necessary to start from the beginning, starting from the selection of the stone, the necessary stone repair and protective treatment and scientific construction methods.
We have done some tests, and the humidity of the stone that has problems on the ground is mostly above 5%. If the stone always maintains such a humidity, even if the cracks and holes are repaired, new ones will appear in other parts after a long time. problem. In this way, the problem of eliminating water sources arises.
In fact, many buildings will not have high humidity in the ground foundation part after a period of time, and there will be no real water source. The reason why the stone can maintain a high temperature for a long time is that the water is in the stone as pointed out in the previous reason analysis. A vicious circle is formed inside, that is, the water and moisture on the back of the stone destroy the stone. When this part of the water does not completely run away, the water on the surface runs along the cracks and loose parts of the stone. Moisture acts in the stone for a long time, and the improper ground maintenance method reduces the air permeability of the stone. It is impossible for the stone to have no problems.
In fact, here we have also found the key and idea to solve the problem, remove the water on the stone and the back of the stone, and then repair and make up for the damage of the stone. The stone is damaged by water again. Therefore, it is best to keep the stone dry and tidy when paving the ground to avoid a vicious circle.
