Recent Developments in Inspection Techniques for Corrosion Damaged Concrete Structures

Improved procedures for inspecting both reinforced concrete and prestressed concrete structures, with regard to determination of the embedded steel components are discussed. Prototype ultrasonic procedures recently developed to determine the condition of prestressed pretensioned tendons in concrete will be discussed. The application of electrochemical surface mounted systems for estimating the rate of corrosion of reinforcing steel and other embedded steel components in large concrete structures will also be described. In particular, the ability to obtain rate of corrosion data over the concrete surface and presenting it as iso-corrosion rate contours will be highlighted.
