Anonymous users2024-01-23The main reason for the anti-alkali of the wall, commonly known as cement frosting, is that the cement product calcium hydroxide reacts with carbon dioxide in the atmosphere to generate calcium carbonate and deposit it on the surface of concrete products; Or: in a solution of calcium hydroxide, a hydration product, when the water evaporates, the calcium hydroxide crystallizes in the cracks of the concrete and gathers on its surface. In addition, limestone or building sand contains a certain amount of soluble alkali-containing organic matter, and the hydroxide, carbonate or other alkali salt solutions formed by them can easily and quickly seep out "frost salts" on the concrete surface and frost.
A good way to deal with it is to recommend that you re-shovel the peeled ones and shovel them to the bottom layer to clean the walls. Then use the Alkali Elimination No. 1 to mix it up and apply it.
