Salt Damage To Sesame Ash Stone Is Not Very Big

- Sep 10, 2019-

Everyone should think about the damage of salt sesame ash stone. In fact, the damage of salt to sesame ash stone is very big. Why do you say that?

Salt damage to sesame ash stone is second only to water. Its damage to sesame ash stone is represented by: crystallization weathering, crystallization pressure, hydration pressure, moisture absorption, and swelling. stress. Because of the action of salt, the sesame ash stone becomes loose, which constitutes the most important weathering factor of gray. The existence of salt is the crystal salt of sesame ash stone itself, and the second is the combination of the gray component of the day and the acid gas in the air. salt.

In the construction of sesame ash stone cement, lime, soil, food, sea water, industrial production, etc., some cleaning agents will pass into the sesame ash stone through the fine pores and fine cracks of the sesame ash stone through the capillary scene. After the salt forms crystals in the sesame ash stone, a great pressure occurs, that is, the crystallization pressure, and the greater the crystallization pressure, the greater the damage to the sesame ash stone. Some salts are also converted into hydrates that crystallize from the beginning under certain conditions, which in turn occupy a larger volume, and additional pressure, ie hydration pressure, occurs. There are torrent molecules in the molecular formula of gypsum. Following the change of temperature, the pressure changes accordingly, and the repeated stress changes. After all, some of the sesame ash stone changes are powdery, broken, and scaly. The damage of salt to sesame ash stone is usually repeated by means of water and wind, and it is repeatedly dissolved in the gray surface of the Wen--------------------------------
