The deterioration caused by the corrosion of reinforcement steel in reinforced and prestressed concrete poses a significant threat and requires careful attention. Failure to address this issue could lead to loss of life and substantial financial consequences. One specific application of concern is in prestressed concrete cylinder pipes, extensively utilized for water and wastewater conveyance. The predominant challenge in these pipes is the corrosion of prestressed wires, which has the potential for catastrophic failure. In the case of the Man-made River in Libya, early detection of corrosion becomes crucial to prevent water disruptions in residential and industrial areas. This study explores the application of the Acoustic Emission (AE) technique for detecting and pinpointing the initial stages of corrosion, as well as categorizing various types of cracks. Preliminary findings suggest that AE effectively identifies corrosion in representative structures, offering the capability to pinpoint and classify crack locations and types.
