What are the effects of prolonged exposure to humidity on concrete?
Prolonged exposure to humidity significantly impacts concrete's structural integrity and longevity. Moisture absorption weakens the material, leading to cracks, spalling, and reduced load-bearing capacity. Over time, high humidity accelerates chemical reactions like alkali-silica reaction (ASR) and corrosion of embedded steel reinforcements, further degrading the concrete. Freeze-thaw cycles in humid conditions exacerbate damage by expanding trapped water. Preventive measures, such as proper sealing and moisture-resistant mixes, are essential to mitigate these effects and ensure long-term durability. Understanding these risks helps in designing more resilient concrete structures for humid environments.
