What are the effects of freeze-thaw cycles on concrete outdoor lounger integrity?
Freeze-thaw cycles significantly impact the integrity of concrete outdoor loungers, leading to potential structural damage over time. When water penetrates the porous surface of concrete and freezes, it expands, creating internal pressure that can cause cracks, spalling, and surface deterioration. Repeated cycles worsen these effects, compromising durability and safety.
To mitigate damage, use air-entrained concrete, which contains tiny air pockets to absorb expansion pressure. Proper sealing and drainage also reduce water infiltration. Regular maintenance, such as resealing and inspecting for cracks, can extend the lifespan of concrete loungers in cold climates. Understanding these effects helps in designing and maintaining weather-resistant outdoor furniture.
