How does the carbonation process affect the longevity of concrete outdoor bar stools?
The carbonation process significantly impacts the longevity of concrete outdoor bar stools by reacting with calcium hydroxide in the concrete to form calcium carbonate. This chemical reaction reduces the alkalinity of the concrete, weakening its protective layer and making it more susceptible to corrosion, especially in steel-reinforced stools. Over time, exposure to CO2 in the air accelerates this process, leading to cracks, surface erosion, and structural instability. To prolong durability, using high-quality concrete mixes, sealants, or stainless steel reinforcements can help mitigate carbonation effects. Proper maintenance and protective coatings are also essential for extending the lifespan of outdoor concrete furniture.
