What issue can arise from pyrite in construction materials?

The presence of pyrite in construction materials, particularly in concrete, can lead to significant structural damage. Pyrite can undergo oxidation when exposed to moisture and air, which generates sulfuric acid. This process can cause the formation of expansive products within the concrete, leading to cracking, deterioration, and ultimately a loss of structural integrity over time.

Unlike issues such as electrical hazards, water damage, or insulation failure, which are associated with different underlying causes, the specific chemical reactions induced by pyrite directly compromise the material's strength and stability. Addressing this issue often requires significant repairs or even replacement of affected structures to ensure safety and compliance with building standards. Understanding and mitigating the risks associated with pyrite is crucial in construction and real estate practices to maintain durable and safe structures.
