Technology always advances faster than the development of codes, specifications, and standards. Recent innovations in materials and corrosion control technologies have enabled designers and architects to meet performance-based specifications at lower life cycle cost. This one-day course focuses on use of the state-of-the-art emerging technologies for repair and rehabilitation of bridges and other concrete structures. These technologies include: conductive concrete, press-on zinc hydrogel anode CP system, snap-on zinc mesh anode CP system, electrochemical chloride extraction, electrochemical realkalisation, cathodic protection, duplex/ stainless steels and alloys reinforcements. Most of these emerging technologies are also increasingly used for corrosion prevention in new concrete structures. Application examples and case studies will be presented to demonstrate the potentials of these promising technologies in the new millennium.
