PATOLOGIAS EM CONCRETO ARMADO E SEUS MÉTODOS DE RECUPERAÇÃO ESTRUTURAL

Abstract

Reinforced concrete, a widely used material in civil construction due to its durability and strength, is subject to changes over time due to interactions between its components, such as cement, sand, gravel, water, and steel. Often, these interactions result in anomalies that can compromise the structure's performance and lead to undesirable aesthetic effects. Thus, the primary objective was to list the most common pathologies found in reinforced concrete structures, as well as the techniques used for their rehabilitation. To achieve this goal, the following specific objectives were highlighted: provide a brief historical overview of the use of reinforced concrete in civil construction; list the main pathologies present in reinforced concrete and demonstrate the importance of their correct identification; and discuss the use of recycled construction concrete. The methodology employed in this research was literature review. In conclusion, it was observed that the most common causes of these defects in reinforced concrete structures are excessive dynamic or static loads, structural movement due to poor installation, excess water or high cement content, high heat of hydration in cement, weathering attacks, and chemical attacks reacting with environmental agents
