cementtikaivokset
Cementtikaivokset refers to a phenomenon observed in certain concrete structures where a whitish, powdery deposit forms on the surface. This deposit is primarily composed of calcium carbonate, a byproduct of a chemical reaction between calcium hydroxide in the concrete and carbon dioxide from the air. Calcium hydroxide is a soluble component of cement hydration and can migrate to the surface of the concrete. When exposed to atmospheric carbon dioxide, it reacts to form insoluble calcium carbonate.
This efflorescence is generally a surface phenomenon and does not typically indicate a structural defect in
While cementtikaivokset is usually harmless, it can sometimes be mistaken for more serious issues like spalling
