What are the effects of acidic fertilizers on concrete bench integrity?
Acidic fertilizers can significantly compromise the integrity of concrete benches over time. When fertilizers with low pH levels come into contact with concrete, they initiate a chemical reaction that breaks down the cement binder, leading to surface erosion, cracking, and structural weakening. The acidity accelerates corrosion of reinforcing steel within the concrete, further reducing durability. High concentrations of ammonium-based or sulfur-containing fertilizers are particularly harmful. To mitigate damage, consider using neutral pH fertilizers, applying sealants to concrete surfaces, or rinsing benches after fertilizer application. Regular maintenance and prompt repairs can extend the lifespan of concrete benches exposed to acidic substances.
