Abstract

Ignoring the fact that steel and concrete are among the building materials that are used in civil engineering more often than any other material, people are preoccupied with the lifetime of the material. This is due to the fact that reinforced concrete is one of the construction materials that has the lowest overall cost. The corrosion of steel in concrete is the most worrisome problem because it accelerates the degradation of concrete infrastructure and is the major driver of the problem. Other concerns include concrete structures that have been affected by corrosion, which undergo a gradual process of structural degradation comprising numerous distinct stages over the period of the structure’s service life. This process occurs throughout the lifespan of the structure. In reinforced concrete structures, corrosion is one of the most prevalent factors contributing to structural collapse. These phases include the onset of corrosion, cracking of concrete, excessive deflection, and finally, the collapse of the building as a consequence of the loss of structural strength. All of these stages lead to the last step, which is the collapse of the structure. Monitoring is being provided for an increasing number of concrete structures, with the goal of extending the useful life of these structures. A wide range of damage detection techniques, including explosive and nondestructive approaches, have been developed over the last several decades. This was performed to investigate the changes caused by corrosion.
