How does the carbonation process of concrete affect outdoor lounger longevity?

The carbonation process of concrete is a natural chemical reaction where carbon dioxide from the air penetrates the material, reacting with calcium hydroxide to form calcium carbonate. While this process can strengthen concrete over time, it may also lead to reduced alkalinity, making the material more susceptible to corrosion of embedded steel reinforcements in reinforced concrete loungers.

For outdoor loungers, prolonged exposure to moisture and CO2 accelerates carbonation, potentially compromising structural integrity. However, high-quality concrete mixes with low permeability and proper sealing can slow carbonation, extending the lounger's lifespan. Regular maintenance, such as resealing and avoiding prolonged water exposure, further enhances durability.

Understanding this process helps in selecting weather-resistant concrete loungers and adopting care practices to ensure long-term outdoor use.
