Abstract:
The durability of reinforced concrete structures is a critical factor in maintaining long-term safety and functionality, having a direct impact on maintenance and repair costs. Exposure to aggressive environmental conditions such as freeze-thaw cycles, chemical or atmospheric agents, and water infiltration can accelerate degradation processes. Among the most common mechanisms of deterioration is corrosion of steel reinforcement, which occurs in the presence of water and oxygen, aggravated by factors such as chlorides or carbon dioxide. Chemical degradation, caused by acids and salts, affects the internal structure of concrete, while erosion and cracking due to shrinkage and expansion caused by temperature can compromise the integrity of the construction elements. To prevent such damage, rigorous design and use of high-quality materials capable of withstanding aggressive environments is required. Advanced protective measures, such as applying special coatings on reinforcements or using additives, help to extend the service life of the construction. Thus, durability not only ensures the stability and safety of the structure, but also brings long-term economic benefits, reducing the need for frequent rehabilitation and contributing to the sustainability of modern construction.
